The San Diego Chargers will have to fill two coaching vacancies on the team's offensive coaching staff, with the Tennessee Titans announcing Friday that head coach Ken Whisenhunt hired Chargers tight end coach Jason Michael.

Michael, 35, spent three seasons coaching tight ends in San Diego. The promotion offers a move closer to home for Michael, a native of Louisa, Ky.

The Chargers hired quarterbacks coach Frank Reich to serve as the team's offensive coordinator to replace Whisenhunt, creating a vacancy at quarterbacks coach. Now, San Diego coach Mike McCoy also will have to replace Michael.

Chargers general manager Tom Telesco said this week his organization has been proactive in filling the vacant coaching positions.

“The great thing about Mike [McCoy] is he is very detailed and prepared,” Telesco said. “He has a list of people that if an opening comes available, this is the people he will be looking at. I have been in the league long enough to where I know a lot of people. You are always prepared for that. Usually it's not going to be a cold call resume coming in.”
