NASHVILLE – The Titans are bringing a familiar face back to the roster in center Hroniss Grasu.

To make room on the 53-man roster, the Titans released receiver/return man Darius Jennings.

The transaction comes at a time when the Titans are monitoring the condition of starting center Ben Jones, who missed practice on Wednesday and is in the team's concussion protocol. Also, guard Rodger Saffold was also limited in Wednesday's session with a concussion.

In Sunday's game against the Buccaneers, lineman Jamil Douglas stepped in and played center when Jones left the game for a snap.

The Titans promoted receiver/return man Kalif Raymond from the practice squad to the 53-man roster prior to Sunday's game vs. Tampa Bay and his only return went for 45 yards. Jennings, who was inactive for Sunday's game, handled the team's kickoff return duties the first seven games of the season.

Grasu (6-3, 301) joined the Titans earlier this offseason after previously spending time with the Bears, Ravens and Dolphins. He entered the NFL in 2015. Grasu was signed to the active roster in September after being released at the end of training camp, but he did not play in a game. He was released again earlier this month during a flurry of roster moves by the team before being re-signed today.

Overall, Grasu has 17 games of NFL experience, including 13 starts at center.
