Philadelphia Eagles guard Evan Mathis left Sunday's game against the Jacksonville Jaguars with what appeared to be a knee injury.
Mathis had his leg caught under a pile of players as he went down awkwardly and he was carted to the locker room after being helped off the field.
Already trailing the Jaguars 17-0, the Eagles are off to a surprisingly slow start, and if Mathis is out for any significant period of time, it would be a huge loss for their offense.
