Bradford fumbled, and the ball was recovered by Ngata who scored his first career regular season touchdown. On October 2, 2011, during the Ravens game against the New York Jets, Ngata sacked Jets quarterback Mark Sanchez, causing Sanchez to fumble the ball. Ravens linebacker Jarrett Johnson picked up the fumble and returned it for a touchdown. The Ravens won the game by a score of 34–17.
