Stanford's Ty Montgomery will probably miss Saturday's game vs. Notre Dame because of a lower body injury. (US Presswire)

Pac-12 Injury Report

WR Ty Montgomery, Stanford, (lower body)

Next game: at No. 7 Notre Dame, Saturday, 3:30 p.m. ET (NBC)

Montgomery probably won’t play Saturday, according to Stanford coach David Shaw. He’s second on the team with 18 receptions for 168 yards and would potentially help stretch the Irish’s staunch run defense. Here’s more on Montgomery’s injury from our Eye on College football blog.  

QB Sean Mannion, Oregon State, (knee)

Next game: at BYU, Saturday, 3:30 p.m. ET (ABC)

Mannion had surgery this past week on a slight meniscus tear and is out this weekend as the No. 10 Beavers travel to BYU. His backup, junior Cody Vaz, hasn’t seen meaningful time since 2010 and has just 48 career passing yards.

CB Marc Anthony, California, (knee)

Next game: at Washington State, Saturday, 10:30 p.m. (Pac-12 Network)

Anthony, who has 34 tackles at cornerback this year, is a game-time decision. He injured his knee last weekend against UCLA and his absence could severely impact the Bears secondary against Washington State, which averages 315 yards per game through the air, 15th most in the country.

S Ray Polk, Colorado, (ankle)

Next game: vs. Arizona State, Thursday, 9 p.m. ET (ESPN)

Polk hasn’t played a game since injuring his ankle in the season opener but is expected to play Thursday night. He should help galvanize an inexperienced secondary that has been gashed through the air. As a whole, the Buffaloes are allowing 39.4 points per game.

WR Darius Bell, UCLA, (rib fracture)

Next game: vs. Utah, Saturday, 3 p.m. ET (FOX)

Bell fractured his rib last weekend in the loss to California and will be out for the next two to four weeks. He has averaged a team-high 20.3 yards per catch this season on seven receptions.

SEC Injury Report

LT Alex Hurst, LSU, (personal)

Next game: vs. No. 3 South Carolina, 8 p.m. ET (ESPN)

Coach Les Miles said after Wednesday’s practice that "Alex had kind of a nick and some issues that are personal to him and has missed some time. We don't expect that he will miss the back end of the week. ... (We) expect him to play based on things that have not been worked out yet." Hurst has been integral to the Tigers’ rushing game, which has averaged nearly 200 yards per game.

RG Josh Williford, LSU, (head)

Next game: vs. South Carolina, 8 p.m. ET (ESPN)

Williford is questionable due to a head injury he suffered in last week’s 14-6 loss at Florida. If he doesn’t play, it would be another huge loss for LSU’s battered O-line.

LB Jelani Jenkins, Florida, (hamstring)

Next game: at Vanderbilt, 6 p.m. ET (ESPNU)

Jenkins is considered probable despite pulling his hamstring in last week’s win over LSU. He had missed the previous two games with a fractured thumb. “We’re pushing Jelani as hard as we can to get him ready to play,” defensive coordinator Dan Quinn told the Gainesville Sun.

QB Patrick Towles, Kentucky, (ankle)

Next game: at Arkansas, Saturday, 7 p.m. ET (FSN)

Towles made his debut last week against Mississippi State, but the true freshman had to leave the game with a sprained ankle. He's not expected to play against Arkansas, meaning fellow freshman Jalen Whitlow will likely start and play the whole game at QB. Whitlow is the third-string quarterback behind injured players Maxwell Smith and Towles. He has 199 yards and two interceptions on the season.

TE Chris Gragg, Arkansas, (leg)

Next game: vs. Kentucky, Saturday, 7 p.m. ET (FSN)

Gragg has a deep bone bruise and coach John L. Smith said on Wednesday that he is "very, very doubtful this week." His backup, Austin Tate, had four catches for 44 yards last week at Auburn. 

TE Malcolm Johnson, Mississippi State, (pectoral)

Next game: vs. Tennessee, Saturday, 9 p.m. ET (ESPN2)

Johnson missed the first five games of the season, but he has been upgraded to probable this week. He had 11 catches for 206 yards and three touchdowns as a freshman in 2011.

Oklahoma State QB Wes Lunt is questionable for Saturday's game vs. Kansas due to a knee injury, which may mean a second consecutive start for backup J.W. Walsh. (US Presswire)

Big 12 Injury Report

RB Shawne Alston, West Virginia, (thigh)

Next game: at Texas Tech, Saturday, 3:30 p.m. ET (ABC)

Alston’s thigh bruise has kept him out the past three weeks, and his injury has lingered longer than anyone expected. His status is still questionable and will depend on how he practices this upcoming week. Fortunately for the Mountaineers, Andrew Buie is making Alston’s loss much more bearable. Against Texas, Buie rushed for 207 yards and two touchdowns.

RB Malcolm Brown, Texas, (ankle)

Next game: vs. No. 13 Oklahoma, Saturday, 12 noon ET (ABC)

Brown is questionable for Saturday’s Red River Shootout against Oklahoma. He missed last weekend’s loss to West Virginia, but his backups, Johnathan Gray and Joe Bergeron, combined for 132 yards and four touchdowns. Fortunately for the Longhorns, LB Jordan Hicks (hip), their most experienced player at the position, has been practicing this week and may be able to go Saturday. In the two games he’s missed, the Longhorns have given up 467 rushing yards.

QB Wes Lunt, Oklahoma State, (knee)

Next game: at Kansas, Saturday, 3:30 p.m. ET

Lunt is questionable for Saturday’s game against Kansas, but if he can’t play, backup J.W. Walsh will start for the second consecutive game. It may not matter which quarterback is under center since the Cowboys have averaged 55.8 points per game this year -- the best mark in the country -- and the Jayhawks (1-4) have given up nearly 30 points per game.

RB Tony Pierson, Kansas, (eblow)

Next game: vs. Oklahoma State, Saturday, 3:30 p.m. ET

Pierson practiced this week with a brace on his left elbow and is expected to play Saturday against Oklahoma State. As Rapid Reporter C.J. Moore pointed out, after Pierson, who scored the game’s first touchdown last week vs. Kansas State, was injured, the Jayhawks’ offense was never the same. Before the injury, he was the Jayhawks’ most effective weapon with six receptions for 63 yards and the score.

Big Ten Injury Report

QB MarQueis Gray, Minnesota, (ankle)

Next game: vs. Northwestern, Saturday, noon ET (ESPN2)

Gray has missed the past two games with a high-ankle sprain and got an extra week of recovery during Minnesota’s bye week. The coaching staff hasn’t made a decision yet whether the scrambling quarterback will play or not. As Northwestern coach Pat Fitzgerald described it, Gopher coach Jerry Kill is taking the “Call me maybe,” approach with Gray.

TE Dion Sims, Michigan State, (ankle)

Next game: vs. Iowa, Saturday, noon ET (ESPN)

Sims injured his ankle in the Spartans’ comeback win over Indiana and will be out for Saturday’s game against Iowa. With 24 receptions for 313 yards, the 6-5 junior is the team’s leading receiver and first-year quarterback Andrew Maxwell’s favorite target.

RB Damon Bullock, Iowa, (concussion)

Next game: at Michigan State, Saturday, noon ET (ESPN)

Bullock has missed the past two weeks with a concussion suffered against Northern Iowa, and his injury was partially responsible for giving surprising tailback Mark Weisman an opportunity. Coach Kirk Ferentz said that Bullock will play Saturday and share carries with Weisman.

RB Ralph Bolden, Purdue, (knee)

Next game: vs. Wisconsin, Saturday, noon ET (Big Ten Network)

There was talk that Bolden could’ve seen his first action this season last week against Michigan, but Purdue coach Danny Hope wanted his 2011 leading rusher to have a few more snaps in practice both with the ball and picking up defensive blitzes. “We are a lot more comfortable about Ralph playing this weekend, and I think Ralph is more comfortable as well,” Hope said on the Big Ten teleconference. Getting Bolden his first action in the team’s biggest game of the season is a risky move, but the Boilermakers could likely use him after rushing for just 56 yards last week against Michigan.

CB Terry Hawthorne, Illinois, (concussion)

Next game: at No. 25 Michigan, Saturday, 3:30 p.m. ET (ABC)

Hawthorne suffered a concussion on a scary hit last weekend at Wisconsin and was taken off the field in an ambulance. Before being cleared to play this weekend in Ann Arbor, he still has to pass a number of tests, including a concussion physical and an endurance exam.

Virginia wide receiver Tim Smith has missed three of the past four games with a lower body injury and is questionable for Saturday's game against Maryland. (US Presswire)

ACC Injury Report

QB Sean Renfree, Duke, (elbow)

Next game: at Virginia Tech, Saturday, 12:30 p.m. ET (ESPN3)

Renfree is listed as probable on the Blue Devils injury report in anticipation of this weekend’s game against the Hokies. He missed last week’s win against Virginia while his backup, Anthony Boone, threw for 212 yards and four touchdowns in his first collegiate start. The two have been splitting practice reps this week.

G David Wang, Virginia Tech, (ankle)

Next game: vs. Duke, Saturday, 12:30 p.m. ET (ESPN3)

Wang, the starting left guard, missed practice on Tuesday and is questionable for Saturday’s game against Duke. The interior of the Hokies’ offensive line has been inconsistent all year, leading to just 131 rushing yards per game, the 92nd fewest in the country.

WR Tim Smith, Virginia, (lower body)

Next game: vs. Maryland, Saturday, 3 p.m. ET (ESPN3)

Smith has missed three of the past four games with an undisclosed lower body injury and is questionable for Saturday’s game. The junior was expected to be a veteran presence among the Cavaliers receivers but has been limited to just eight catches for 144 yards and one touchdown this year.

Big East Injury Report

RB Dominique Brown, Louisville, (knee)

Next game: at Pittsburgh, Saturday, 11 a.m. ET (ESPNU)

Brown hasn’t played all season and the emergence of running backs Senorise Perry and Jeremy Wright has made it increasingly likely that Brown will redshirt this season.  Coach Charlie Strong said on Monday that Brown wouldn’t be used this season unless something happens to the Cardinals’ running back tandem.

LB Daniel Brown, Louisville, (undisclosed)

Next game: at Pittsburgh, Saturday, 11 a.m. ET (ESPNU)

Strong announced that Brown will be out for Saturday’s game. He was injured two weeks ago in the victory over Southern Miss and, unfortunately for Louisville, Brown’s replacement, James Burgess, has been ruled out for this weekend’s game as well. That leaves Champ Lee and true freshman Keith Brown, who led the Cardinals with nine tackles against Southern Miss.

K Kyle Federico, Rutgers, (hip)

Next game: vs. Syracuse, Saturday, noon ET (Big East Network)

Federico has missed two days of practice this week. Coach Kyle Flood said he thinks the freshman will available on Saturday but suggested that his range might be limited. His relative availability hasn’t stopped Flood from holding an open kicker competition between sophomore Nick DeLouisa, freshman Nick Borgese and walk-on Joe Behnke. DeLouisa was the team’s backup, but he missed an extra point after Federico left last weekend’s game against Connecticut.

S Shamarko Thomas, Syracuse, (head)

Next game: at No. 20 Rutgers, Saturday, noon ET (Big East Network)

Thomas, the Orange’s team-leader with 24 tackles, suffered a concussion last week against Pittsburgh, and his status for Saturday’s game remains in question. He has practiced, but as of Thursday, the senior hadn’t been fully cleared to play.
