The Redskins might need another punter for Sunday. Sav Rocca was limited in practice because of an issue with his right knee, prompting the Redskins to bring in free agent punter Chas Henry on Friday.

Henry has a 44.0-yard average on 82 career punts, including 16 this season with Philadelphia. The problem has been his net average, which is 37.6.

Rocca is averaging 44.6 yards per punt this season.

Injury notebook: WR Pierre Garcon (foot) did not practice and won’t practice Friday. Coach Mike Shanahan said he received a pain-killing shot that was more localized than one he had earlier this season. He’s a longshot to play Sunday. CB David Jones (Achilles) did not practice; FB Darrel Young (hamstring), CB Cedric Griffin (hamstring), CB DeAngelo Hall (knee) and DE Doug Worthington (calf) were limited.
