49ers assistant Day takes Bears job

FORT LAUDERDALE, Fla. -- Shane Day, offensive quality control coach for the 49ers, has left the team to serve as quarterbacks coach under new Bears offensive coordinator Mike Martz.

This is an excellent opportunity for Day to progress in his career and work with a talented quarterback, Jay Cutler, in a dynamic offensive scheme.

The staff dynamics in Chicago are certainly curious, with Rod Marinelli coordinating the defense and Martz coordinating the offense. Marinelli fired Martz from his Lions staff two years ago.

The jump from quality control coach to position coach is significant for Day, who spent the last three seasons in the role for San Francisco. Day had been unofficially assisting offensive line coach Chris Foerster in San Francisco, a departure from typical duties for a quality control coach.

Foerster left this offseason and the 49ers hired Mike Solari to replace him. With Ray Brown onboard to assist Solari, it's possible the 49ers will not hire another assistant to replace Day. They could just divide duties a little differently.
