The first NFL coach firing occurred on Monday, with the Titans letting go of Brian Callahan, who had a 4-17 record with the team.
The Titans, averaging 13.8 points per game, were expected to make a change soon, especially with rookie quarterback Cam Ward.
The loser of Sunday's Dolphins vs. Browns game could send Mike McDaniel or Kevin Stefanski to join Callahan looking for a job.
