according to Brad he'll play as long as the knee is not hurting his performances. according to all accounts, its up to him as to when he'll have surgery. its only minor so there's no need to worry
Here's a link with a bit more on the story: http://espn.go.com/soccer/news/2002/1030/1453231.html I don't understand much about injuries, but the basic story is that some cartiledge popped out, got put back in, and he will eventually need surgery. He says if he has 14 free days he could take care of it then.
