This is not how the Washington Huskies hoped to enter the 2011 season.
Star tailback Chris Polk sat out Thursday night's practice after injuring his knee.
Polk, who rushed for 1,415 yards for Washington last season and opted to return to the Huskies after considering the NFL, tweaked his knee during Wednesday's night practice and had arthroscopic surgery to repair a meniscus injury Thursday morning, coach Steve Sarkisian said.
Polk's injury could potentially keep him out for a couple weeks, but Sarkisian said that although he is a tremendous player and great to have in practices, this will give other players some opportunities to make plays.
It also moves Jesse Callier to the top of the depth chart at tailback.
The Huskies open the season Sept. 3 against Eastern Washington in Seattle.
Jordan Wallace is having knee issues and was planning to get an MRI Thursday night, said Sarkisian.
In Thursday's practice, Sarkisian said that he put more emphasis on spread looks for the benefit of both the offense and the defense. Sarkisian also said that in light of the injuries, this is allowing for some more healthy competition and the opportunity to play more guys, which will come in handy during the second half of season games.
Saturday's scrimmage will be an important one, where the focus will be on situational stuff on offense and defense, the younger players and special teams, according to Sarkisian. This scrimmage will allow the coaches and players to get a feel for what play time will look like this season.
Wide receiver Kasen Williams and running back Bishop Sankey have been jumping out first and foremost to Sarkisian potentially on special teams.
According to Sarkisian, Callier has had some nice runs on the inside and Johri Fogerson has brought a serious attitude to training camp.
In the red zone, Austin Seferian-Jenkins and Williams are starting to feel good about what to do, and the quarterbacks are figuring out that Seferian-Jenkins and Williams can really jump, said Sarkisian.
