NFL.com's Ian Rapoport reported Friday that an MRI confirmed Ngata suffered a sprained medial collateral ligament in Sunday's Super Bowl XLVII win over the San Francisco 49ers, according to a source. The injury will not require surgery.
Ngata left the game in the third quarter after San Francisco 49ers guard Aaron Boone fell into the back of his left leg during a Frank Gore touchdown run. Ngata remained on the field for several minutes before being helped to the locker room. He did not return, sparking fears that the four-time Pro Bowl selection suffered a serious injury.
It was a frustrating, if not fitting, way to close the season for Ngata, who was limited by injuries throughout the year. He finished 2012 with 51 tackles and five sacks before adding 13 tackles in four playoff games.
