The NFL fined Titans defensive coordinator Chuck Cecil $20,000 Thursday for verbal abuse of a game official for his sideline comments in Tennessee’s 42-17 loss to San Diego on Christmas night.

The Titans had just been flagged for roughing Philip Rivers when an official heard Cecil say something. The Titans were penalized another 15 yards for unsportsmanlike conduct.

Coach Jeff Fisher defended his first-year coordinator, saying Cecil was overheard talking to fellow coaches on his headset. Fisher said Cecil will elaborate when he appeals the fine.
