Coach Leslie Frazier said the team was informed the operation by Dr. James Andrews was "successful" and that Peterson was "resting comfortably." In a statement distributed by the team, Frazier wished Peterson a "speedy recovery."
Peterson tore the anterior cruciate and medial collateral ligaments in the knee during last Saturday's game at Washington. He finished his fifth NFL season with 970 rushing yards and 13 total touchdowns.
