Minnesota Vikings running back Adrian Peterson will undergo an MRI tonight on his injured left knee, but a preliminary report from Jason Cole of Yahoo! Sports is that the four-time Pro Bowler has a torn ACL and possibly more damage to his left knee.
On the opening play of the second half, Peterson was hit by Redskins safety DeJon Gomes in the left knee after a three-yard run. Peterson was writhing on the ground in pain and was unable to put any pressure on his left leg while he was helped off the field by trainers.
Peterson was on crutches in the locker room after the game.
“You take a blow to the knee like that, you’re concerned about the ACL and the MCL — those ligaments mainly,” Peterson said according to Tom Pelissero of 1500ESPN.com.
“I don’t know. Just trying to stay as positive as I can and I’ll just find out more once (the MRI results are in).”
