Sources: Dion Lewis has torn left ACL, will miss remainder of season

— -- New England Patriots running back Dion Lewis has a torn ACL and will miss the rest of the season, sources confirmed to ESPN.

An MRI performed Monday revealed the full extent of the running back's injury. The Boston Globe earlier reported Lewis' diagnosis.

He was injured with 5:40 remaining in the third quarter of Sunday's 27-10 win over the Washington Redskins.

Lewis was tackled from behind by Redskins defensive lineman Chris Baker at the end of a 14-yard catch-and-run and television replays showed him reaching for the area of his left knee as the play was ending.

Lewis, who has been a spark plug for the Patriots with his sharp cuts and knack for stopping and starting in an instant, had remained down on the ground as the medical staff came onto the field. He eventually walked off the field slowly under his own power and headed straight to the locker room for medical tests.

Selected by the Philadelphia Eagles in the fifth round of the 2011 draft out of Pitt, Lewis joined the Patriots this past offseason.

He finishes the 2015 season with 234 yards rushing and two touchdowns to go along with two receiving touchdowns for the 8-0 Pats.
