The Ravens confirmed this week that linebacker **Ray Lewis** officially signed his new contract, the terms of which were undisclosed by the team.
Various media reports have stated that Lewis' deal is for three years, while another lists the length at seven years.
The 10-time Pro Bowler agreed to his contract last Wednesday, but was not able to officially sign it. *The Baltimore Sun *reported that the incentive-filled contract needed to be reviewed by the NFL Players Association and the Management Council.
Lewis is coming off a season in which he led the NFL's second-ranked defense with 160 tackles and also posted three interceptions and 3.5 sacks.
Retaining No. 52, who was originally drafted by the Ravens in the first round in 1996, marks a continuation of Baltimore's tradition of defense as it transitions from Rex Ryan to new defensive coordinator **Greg Mattison**.
"He's been a great leader from the start, and I think that will only help us as a defense," said safety **Haruki Nakamura**. "I know for me, as a rookie last year, it was good to hear him tell me how I can succeed as a pro."
