Marvin Lewis signed a one-year contract extension through the 2015 season on Friday.

His previous contract was due to expire following the 2014 season.

"Marvin has earned this commitment for the job he is doing," said Bengals president Mike Brown. "We are one of only five teams to qualify for the playoffs the last three years, and our prospects are bright looking ahead. Marvin is driven to achieve more, and we are happy to secure his leadership of our team beyond the coming season."

He's the most tenured coach in Bengals history and is entering his 12th season. His 90 career victories are the most in Bengals history, by 26 over Sam Wyche (64). Overall, he's 90-90-1 including an 0-5 record in the postseason.
