SAN DIEGO -- As expected, the San Diego Chargers announced that quarterbacks coach Frank Reich will take over as the team's offensive coordinator, replacing Ken Whisenhunt, who accepted a job as the coach of the Tennessee Titans.

"With Frank as offensive coordinator, we will be able to maintain continuity on offense and help maximize the production by (quarterback) Philip (Rivers) and the entire unit," San Diego coach Mike McCoy said in a statement. "He has a great feel for the offense we have created and he has been a valuable asset to Philip and all of the quarterbacks."

Added Chargers general manager Tom Telesco: "Frank is an outstanding football coach with tremendous experience in the league as both a player and coach, including 10 years as a quarterback with the Buffalo Bills in one of the most productive offenses in NFL history. He also has worked with some outstanding coaches and quarterbacks. We're fortunate to have Frank on our staff."

Reich joined San Diego's staff as the quarterbacks coach in 2013, developing a good rapport with Rivers and helping him put together one of the best seasons statistically in his 10-year career.

"He is a heck of a coach," Rivers said. "His steadiness from week to week, the way he helps prepare us and coaches is second to none. His playing career obviously helps and his preparation."

Reich, 52, played 14 years in the NFL, including stints with Buffalo (1985-94), Carolina (1995), the New York Jets (1996) and Detroit (1997-98) before retiring in 1998. After retirement, Reich spent seven years in private business before transitioning back into professional football.

In 2006, he took a coaching internship with the Indianapolis Colts, and in 2008, they elevated him to an offensive assistant position. Reich remained with the Colts until 2012, when he was hired as the wide receivers coach for the Arizona Cardinals, where Whisenhunt served as coach.

A native of Freeport, N.Y., Reich grew up in Lebanon, Pa., where his father was a high school coach. His younger brother, Joe, is currently the coach at Wingate (N.C.) University.
