After 15 seasons, one NFL head coach is leaving the franchise at season's end

His tenure is over.

After 15 seasons with the Cincinnati Bengals, head coach Marvin Lewis is reportedly leaving the franchise.

Rumors emerged just last season that he was planning to leave, but following another eight-loss or more season, Lewis is apparently on his way out.

Over his tenure, Lewis is 123-111-3. He took over as head coach of the Bengals in 2003. He's lead Cincy to six seasons of 10 or more wins, including the best stretch of his career with the Bengals, from 2012-2015.

He's won one Super Bowl, as an assistant for the 2000 Baltimore Ravens.

Lewis spent the first 11 years of his career as a college assistant, before jumping to the Pittsburgh Steelers for three seasons, joining the Baltimore Ravens in his first coordinator position (defensive) with the Ravens from 1996-2001 and eventually landing one year as defensive coordinator with the Washington Redskins.

Schefter later said he expects to see anywhere between 8-10 head coaching changes this offseason.
