The first NFL coach firing occurred on Monday, with the Titans letting go of Brian Callahan, who had a 4-17 record.
The Titans, averaging 13.8 points per game, were due for a change, and now they face New England in Week 7 under interim coach Mike McCoy.
The loser of the Dolphins vs. Browns game could potentially lead to Mike McDaniel or Kevin Stefanski being fired next.
With Tennessee averaging only 13.8 points per game (31st) with rookie No. 1 overall pick Cam Ward at quarterback, the Titans were seemingly headed for a change sooner than later.
