An MRI last night revealed a tear to his anterior cruciate ligament, the National Football League team said. Recovery from a torn ACL may take as long as nine months, according to MedicineNet.com.
Peterson, 26, who scored a touchdown on a one-yard run in the second quarter, left the game in pain after he was tackled by Redskins safety DeJon Gomes at the start of the second half.
“Anytime you take a blow to the knee like that, you’re concerned about the ACL, MCL,” Peterson told reporters before the results of the MRI were known. “I’m trying to stay as positive as I can.”
Head Coach Leslie Frazier will give an update tomorrow, the team said. Peterson has played with the Vikings since 2007.
