New England Patriots running back Dion Lewis left Sunday’s game against the Washington Redskins in the third quarter with a knee injury and did not return.

According to ESPN’s Adam Schefter, Lewis has no swelling in his knee, but has a loose ACL. He will undergo an MRI.

During the third quarter, Lewis made a 14-yard catch, and held his left knee as he fell to the ground. He was down for some time, and helped off the field.

Before leaving, Lewis recorded 14 yards on four carries and caught four passes for 39 yards. He entered the game with 569 all-purpose yards in six games.

The Patriots had already lost offensive tackle Sebastian Vollmer to a head injury, which left them with just five healthy offensive linemen. He did not return.
