49ers fire embattled Offensive Coordinator Jimmy Raye

The San Francisco 49ers have fired offensive coordinator Jimmy Raye, according to a league source.

Quarterback coach Mike Johnson will take over offensive coordinator duties, according to the source.

49ers coach Mike Singletary and Raye have not seen eye-to-eye about the reasons for the team’s struggling offense.

The 49ers, 0-3, entered the season amidst heavy playoff expectations and passed on several quarterbacks to stay with starter Alex Smith, who has been inconsistent during the team’s three losses.
