NASHVILLE, Tenn. -- Running back David Fluellen is working to return from knee surgery and could be ready to play in the Titans' season opener in Cleveland on Sept. 8.FluellenBucsPractice

It's unclear when exactly Fluellen got hurt or what exactly he did, but he's been out of action since before the team's preseason opener on Aug. 8. With Derrick Henry also out, Jeremy McNichols has worked behind Dion Lewis in the two preseason games, averaging 4.1 yards per carry on 14 chances.  

Fluellen suffered a knee injury against the Patriots Nov. 11, 2018 and while the Titans held out hope he could return he went on IR Dec. 20.

Fluellen is a favorite of Mike Vrabel and the third-year running back from Toledo fits right in with the coach's frequent message that the team will treat a player as the player treats the team. It would be a big surprise if Fluellen didn't maintain his spot on the roster as the team's third running back. [Unlocked]

Aside from backing up Henry and Lewis, Fluellen has also been a key special teamer. He added 15 pounds this offseason so that he can also be utilized as an H-back, a development he discussed with me at the start of camp.

Fluellen's ability to effectively contribute in that role could have a bearing on how the Titans move forward with their tight ends behind Delanie Walker and Jonnu Smith.

Anthony Firkser is a great pass-catcher. MyCole Pruitt is typically a "Y," aligning and blocking on the line, while Ryan Hewitt plays the "H." Vrabel recently said each of them is working at the other spot to become more versatile.

But perhaps a Prutt-Fluellen combination would offer an extra capacity for both.
