Jason Campbell will not require surgery on his injured left knee, but he will be sidelined for the Redskins' Week 15 game against the New York Giants, head coach Joe Gibbs said.
Campbell suffered a dislocated kneecap in the Redskins' 24-16 win over the Chicago Bears on Thursday night.
Athletic trainers put Campbell's knee back in place on the field shortly after the injury on Thursday. He had an MRI on Friday to determine if there were any bone chips in the knee.
"It looks like we're okay from that standpoint, which means no surgery," Gibbs said, "[The injury] is extremely painful for Jason right now, but we know it'll just be a matter of the knee healing up."
Asked for a timetable on Campbell's return, Gibbs replied: "We just got all of the information back and I think it will be a while for the doctors to have a chance to look at everything and give a best guess of how long it would be before he could play.
"We do know it is not something where he will have to have surgery. It will be a matter of him healing up and being able to get back over that. We have not gotten to a point where we can say how long."
Campbell said on Friday that it's "hard to say" if he'll come back this season.
"We'll see how things improve over the next couple weeks," Campbell said. "Right now the thing I have to do is stay off of it as much as possible and let the swelling get out of it. Then we'll see what happens."
Would he be surprised if he came back?
"I'm not going to rule myself out of anything," Campbell replied. "I'm always going to stay positive. The one thing you don't want to do is be ignorant about it. You want to be smart about it. So I'll take it as a week to week thing."
Todd Collins will take over at quarterback in Campbell's absence. Collins will be backed up by Mark Brunell.
"If you look around the league, you have to have a quarterback that can come out to play because you never know when something like this is going to happen," Campbell said.
"The main thing for Todd is that he has an opportunity. He was with Coach [Al] Saunders in Kansas City before he got here, so he already knows the offense and he can go out there and do what he can do."
