Carolina Panthers Pro Bowl quarterback Cam Newton won't play tonight against the Buffalo Bills.

Newton had offseason ankle surgery.

Sitting out this game is just to guard against Newton getting hurt.

"We've got to get him ready for game day,'' offensive coordinator Mike Shula told ESPN. "Does he need reps? Everybody does because of the newness of our personnel. But we have to be smart.''
