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 only 13.8 points per game with rookie quarterback Cam Ward, were expected to make a change soon.
The loser of Sunday's Dolphins vs. Browns game could lead to Mike McDaniel or Kevin Stefanski losing their job.
