Washington Redskins coach Mike Shanahan sounded resigned Monday to being without tight end Chris Cooley for a significant period of time. He said the two-time Pro Bowl player would have surgery on his fractured left index finger Wednesday, and later will seek additional medical opinions on his troublesome left knee.

When asked exactly how much time Cooley would miss, Shanahan was vague.

“He’s going to get operated on Wednesday on his index finger, and after the surgery, I’ve got to get some more opinions on -- his knee, he did rest it and it swelled up again eventually -- what the doctors think with the finger, with the knee, exactly where he’ll be at. So we’ll listen to opinion over the next few days, especially after the surgery to make a decision for sure.”

Cooley missed the preseason while he waited for his knee to return to full strength after arthroscopic surgery following the 2010 season. In addition to resting the knee, he received platelet-rich plasma (PRP) treatment, and said he had experienced gradual improvement during the first five weeks of the season.

But Cooley returned from the bye week Monday and said his knee had swelled again. He had it drained, and said that it was not a major problem..

Cooley hasn’t missed any games, but hasn’t been a focal part of the offense as he was in years past. He has recorded only eight catches for 65 yards.

Meanwhile, fourth-year pro Fred Davis has overtaken Cooley as the team’s go-to tight end. Davis leads the team with 343 receiving yards. His 22 receptions rank second on the team, and he has one touchdown.
