Peppers left the Detroit game briefly in the first half, but returned to action and finished with three tackles. He missed two games at the end of the 2007 with a similar injury to his right knee, when he was with the Carolina Panthers. Peppers was placed on injured reserve to end that season, but still made the Pro Bowl.
If Peppers misses any time, it's a significant loss for a troubled Bears defense that currently ranks 29th in the league and has surrendered 419.6 yards per game. Even with Peppers on the field, linebacker Brian Urlacher admitted Tuesday: "Defensively, we stink. We can't stop the run, we can't stop the pass."
