No. Like MJD said, "All I'm saying is that he can finish the game on a hurt knee... I played the whole season on one..."
Phillip Rivers played most of a conference title game against the Colts with a torn ACL. I've seen no official word that Cutler had a torn MCL, but even if he did, he should have played.
And as for Urlacher, he's still looking for his jock after Brandon Jackson broke his kankles for him.
According to Wikipedia...
In the 2007 AFC Championship Game, Rivers' was lauded by his teammates and the press for playing the entire game with a torn anterior cruciate ligament, which later required surgery and was ranked among the NFL Top 10 Gutsiest Performances.[13][14] Chris Harry of the Orlando Sentinel said "I don't think anyone will ever accuse Philip Rivers of being soft."[13] Kevin Acee of the San Diego Union-Tribune said, "To go out there and put his knee, and ultimately his career, on the line. It has to go down as one of the gutsiest performances."[13]
