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, were expected to make a change soon, especially with rookie Cam Ward at quarterback.
Under interim coach Mike McCoy, the Titans will face former coach Mike Vrabel and the New England team in Week 7.
The loser of the Dolphins vs. Browns game could potentially lead to the firing of either Mike McDaniel or Kevin Stefanski.
The loser of Sunday's Dolphins vs. Browns (-2.5) game could send Mike McDaniel or Kevin Stefanski to join Callahan looking for a job.
