Fluellen was waived by the Titans on Monday, ESPN's Adam Caplan reports.
Fluellen didn't appear in a game for Tennessee during his brief stint on the active roster. Defensive end Mehdi Abdesmad was signed off the practice squad in a corresponding move.
Fluellen (coach's decision) is inactive for Sunday's game against the Broncos, Jim Wyatt of The Tennessean reports.
With the Titans' two primary backs, DeMarco Murray and Derrick Henry, enjoying sound health this season, Fluellen has yet to suit up in a game. As the fourth-string running back, Fluellen is on the fringe of the 53-man roster and would be an easy cut if the Titans need to add depth at another position.
Fluellen had a good preseason but it wasn't enough to get him a spot on the 53-man roster. He'll be a candidate for the practice squad if he clears waivers.
Fluellen turned three carries into 13 yards in Saturday's preseason opener against the Chargers.
Fluellen entered this game buried beneath a bevy of other running backs on the depth chart, and this performance didn't move the needle much. He seems destined to be released by the Titans for a second straight season.
