Vikings RB Adrian Peterson tears ACL

An MRI confirmed Minnesota's worst fears - 26 win over the Washington Redskins.

Peterson, who was playing in just his second game after missing the previous three with a high ankle sprain, was helped off the field after taking a helmet to the knee from Redskins safety DeJon Gomes on a run up the middle early in the third quarter.

Peterson had rushed for 38 yards and a touchdown before leaving the game.

Head coach Leslie Frazier will give a further update Monday at his press conference.
