Though the Minnesota Vikings were calling Adrian Peterson's injury a "knee sprain" on Saturday afternoon, the team's worst fears were reportedly confirmed upon further examination. Peterson reportedly suffered a torn ACL, an injury confirmed by an MRI late Saturday night. Peterson went down during the Vikings' 33-26 win over the Washington Redskins, with his knee bending in gruesome fashion.
The report comes from ESPN's Adam Schefter.

ESPN's Josina Anderson added that Peterson tore both his ACL and MCL, making the injury even worse.
With just one game remaining in the 2011 season and the Vikings way out of contention, the short-term impact of Peterson's injury isn't the issue here. However, after suffering such a devastating knee injury, it's unclear how Peterson will respond as he works to rehab through the summer and, perhaps, into next season. Facing major reconstructive surgery, Peterson has a long road ahead to recover from an injury that could significantly alter his career going forward.
