SANTA CLARA, Calif. -- Rob Chudzinski, the Cleveland Browns' offensive co-ordinator for the past two seasons, is interviewing with 49ers coach Mike Singletary for San Francisco's vacant offensive co-ordinator job.

Former St. Louis coach Scott Linehan and Indianapolis receivers coach Clyde Christensen interviewed with the 49ers on Friday.

Chudzinski was praised in 2007 when Cleveland's offence scored 402 points and finished eighth in the NFL, but his unit slumped to 31st this season, contributing to coach Romeo Crennel's firing. Chudzinski got a contract extension from Cleveland last season, but isn't expected to stay on new coach Eric Mangini's staff.

The 40-year-old Chudzinski is an up-and-coming offensive mind, but he was known for a pass-first philosophy with Cleveland quarterbacks Derek Anderson and Brady Quinn, which might not fit Singletary's vision of a run-based offence in San Francisco.

The 49ers are searching for their seventh offensive co-ordinator in seven seasons after Singletary fired Mike Martz late last month. San Francisco's offence improved under Martz after being the NFL's worst in two of the previous three seasons.
