One week since the Cowboys arrived in California, and it’s been quite busy for the athletic training staff.

More than 20 players have an injury and are either out for a few weeks, just returning to practice, in-and-out of practice or something that was suffered Saturday.

The latter includes WR Miles Austin, who missed the end of practice after tweaking his hamstring. Austin missed six games in 2011 with two hamstring injuries. He missed three games early in the season with a left hamstring and then three more with a right hamstring injury. Also, Austin missed most of training camp and all of the preseason dealing with hamstring issues.

Cowboys VP Stephen Jones said the club is not concerned with Austin’s latest injury, but did say a WR “or two” could be added.

The club lost rookie Cole Beasley, who told coach Jason Garrett he’s not interested in playing football at this time. Fellow rookie Saalim Hakim will be out 7-10 days after suffering a broken bone in his left ring finger.

The Cowboys are also down a few RBs after Phillip Tanner broke a bone in his hand and needs surgery in Dallas. Rookie Lance Dunbar strained a hamstring and will be out a few days.

Stephen Jones said there's no reason to panic but does expect a few new players to be signed.

“Two or three. Probably a back and a receiver, and maybe another receiver,” Jones said. “That’s really the only place for concern right now. We’ve got a lot of guys coming back next week.”
