NASHVILLE, Tenn. – The Titans have made some additional roster moves following Thursday's preseason opener.

He spent the entire 2016 season on Oakland's practice squad before being released. He spent time on the Titans practice squad in 2017, and briefly spent time with the Giants this offseason.

Caldwell (5-8, 185) played at Louisiana-Monroe before being drafted by the Browns in the fifth round of the 2016 NFL Draft. Caldwell spent time on Cleveland's practice squad and active roster in 2016. He played in one game for the Browns in 2016.

The team's roster count is currently 89.
