Chargers running back Ryan Mathews had a tough game Sunday against the Seahawks.

Mathews gained 31 yards on 11 carries. He caught two passes for 26 yards. Mathews had to be carted off the field after recovering a fumble. He managed to come up with the ball, but injured his right knee on the play. Mathews is set to have an MRI on his knee Monday.

The Chargers take on the Bills Week 3 if Mathews can go.
