Nick Williams paid the price for his dropped touchdown pass that helped cost the Titans a chance to win in Buffalo on Sunday.
Williams was wide open and dropped the ball after Marcus Mariota had scrambled and found him with just under 11 minutes to play and the Titans trailing the Bills 10-6 at the time.
The drop forced Tennessee to settle for the third of four Ryan Succop field goals, and even though the Titans would eventually take a late lead, they could not hold on against Buffalo. Williams had had a 38-yard punt return earlier in the game that set up Tennessee's first field goal. He also was the intended receiver on a pass from Mariota that was intercepted when there appeared to be some miscommunication between quarterback and receiver on the play.
The Titans also waived third-string quarterback Austin Davis, who was signed two weeks ago when Blaine Gabbert was out with a concussion. Davis did not play in either game he was on the 53-man roster and was a healthy scratch against the Bills as Gabbert returned to back up Mariota.
The Titans also promoted inside linebacker Robert Spillane to the active roster with one of the open spots. The other spot remains open, and the Titans could fill it with a receiver, being down to only four on the roster with Williams' departure.
On Tuesday, the Titans waived running back Dalyn Dawkins to put tight end Anthony Firkser back on the active roster. Dawkins is likely to go back to the practice squad once he clears waivers.
The Titans also added linebacker Nigel Harris to the practice squad and dropped offensive lineman Coleman Shelton.
