Philadelphia Eagles left tackle Jason Peters left Monday night’s game against the Washington Redskins on the back of a cart after injuring his right knee when a pair of players tumbled into the side of his leg.

According to Les Bowen and Jeff McLane of the Philadelphia Inquirer, the initial impression on Peters’ knee is an MCL injury. Peters will have an MRI on Tuesday to determine the full extent of the damage.

If it is only an MCL injury, Peters and the Eagles may feel like they dodged a bullet.
