Even IF this were true, he could easily play QB for the rest of the season assuming it got no worse.
It all depends on the extent of the tear (obviously). Some meniscus tears don't even need surgery. Your meniscus is like an onion and when it tears to a significant extent it slides which will cause your knee to "go out".
That all said, I have a hard time believing that if they legitimately thought there was anything to the knee injury they would've marched him to the locker room with a quickness during that game. I was watching and they pretty much just slapped a brace on it and rolled with it. I don't know that they would have him practising at full speed on it either given his status with the team (starting QB). It just doesn't add up to me.
