"It's highly unlikely offensive coordinator Mike Martz will return to the Bears in 2012, an NFL source said.

Martz has considered his departure from the Bears when his contract expires after this season a foregone conclusion because management offered him only a one-year extension after the team reached the NFC Championship Game last season.

Martz is making $1 million

per year, which is below the median for NFL offensive coordinators. Although it's possible the Bears could offer him a lucrative multiyear extension after this season, that scenario is considered unlikely, the source said."
