Ajayi, the Eagles' No. 1 running back, finished the game with just eight carries for 29 yards in what will be the last game of his season. He tore an ACL, presumably late in a pass-heavy loss to the visiting Vikings on Sunday. Ajayi fumbled at the Vikings' 5-yard line early in the third quarter but returned to the game after that play. His final carry was a 6-yard run in the fourth quarter that was negated by a formation penalty. Curiously, he showed no signs of injury at his locker after the game — certainly not an injury as severe as a torn ACL, especially for a player who has chronic knee problems.
