Cal State Fullerton's Bob Burton is expected to step down, sources told CBSSports.com. 

Burton will likely be replaced on an interim basis by Andy Newman. 

Burton was a long-time junior college coach who was hired back in 2003 to replace Donny Daniels. Burton had been 488-158 in 21 years at West Valley College. 

He leaves Cal State Fullerton after a decade and a 153-122 record. The Titans were 21-10 last season. 

Newman came with Burton from West Valley -- and has been the associate head coach for the past five seasons.
