MRI shows Adrian Peterson has a torn ACL and MCL
An MRI has confirmed that Vikings running back Adrian Peterson has a torn ACL and MCL, according to Tom Pelissero of ESPN1500.com.
Per Pelissero, Peterson won't have surgery for several weeks and he does not have a torn PCL.
Typically the injury takes a minimum of eight months (but usually longer) to heal, which puts the start of the 2012 in jeopardy for Peterson. If/when he returns to the field in 2012, Peterson likely won't be nearly as effective of a runner as he has been in the past. Assuming he makes a full recovery, which is not guaranteed, we may not see that until the 2013 season.
Before suffering the injury, Peterson finished today's game with 12 carries for 38 yards and a touchdown in addition to two receptions for 14 yards. Backup Toby Gerhart carried the ball 11 times for a career-high 109 yards.
If your fantasy league runs through Week 17, Gerhart does not have a great matchup against the Bears but he will obviously get the majority of work.
