JACKSONVILLE – Seth DeValve will miss a second consecutive game.

That's the major injury news for the Jaguars as of Friday – that the veteran tight end will miss a second consecutive game with an oblique injury sustained in practice last week.

The Jaguars (4-6) will play the Tennessee Titans (5-5) in an AFC South game at Nissan Stadium in Nashville, Tennessee, Sunday at 4:05 p.m.

DeValve, claimed off waivers shortly before the regular-season opener, had been the Jaguars' most productive tight end for several weeks. The position overall has struggled this season since a torn anterior cruciate ligament sustained in Week 5 ended tight end James O'Shaughnessy's season.

We'll get into an increased role for rookie linebacker Quincy Williams and other injury news later in this Friday Jaguars update, but the tight end position remains a point of issue for the Jaguars.

DeValve's absence leaves the Jaguars three healthy active tight ends: rookie Charles Jones, veteran Ben Koyack and veteran Nick O'Leary. The Jaguars moved Jones up from the practice squad this week and Sunday will be his first NFL game.

The Jaguars signed O'Leary, who played collegiately at Florida State, as a free agent this week.

Jaguars tight ends have caught 11 passes for 97 yards since O'Shaughnessy's injury, with DeValve catching six of those passes for 68 yards. Koyack has one reception for nine yards this season.  O'Leary caught four passes for 37 yards for the Miami Dolphins this season.

Also around the Jaguars:

*Williams, a third-round selection in the 2019 NFL Draft from Murray State, is expected to get an increased role in the defense Sunday with both Head Coach Doug Marrone and defensive coordinator Todd Wash saying as much this week. Williams, who started the first five games of the season at weak-side linebacker before being replaced in the starting lineup by veteran Najee Goode following a loss to Carolina in which the Jaguars allowed a season-high 285 yards rushing, missed two games with a hamstring injury but is now fully healthy. He said this week he believes he learned from his experience early in the season, when he at times tried to do too much rather than playing within the team's gap-control scheme. "I feel improved," Williams said. "The game's slowing down for me. I got a chance to actually take a few weeks and stand back and see how things are supposed to be played. I watched Najee, who did a great job at the Will spot. Sitting back and getting a chance to be a student of the game helped me a lot." Williams played mostly safety at Murray State in recent seasons, and defensive coordinator Todd Wash said this week Williams learned quickly following being replaced. "After the first week when he was sat down, he came and said, 'Hey, I understand. I'm not out there trying to make plays; I have to do my job,'' Wash said. "I think Quincy learned that early on." Middle linebacker Myles Jack on Friday said, "He's had time to work with coach and spend extra time. I definitely feel like he's more ready to go. It should be good."

*Wide receiver Dede Westbrook returned to practice Friday after missing Thursday's practice with an illness. He was removed from the game status report Friday and is expected to play Sunday. All other Jaguars players who were on the injury report this week other than DeValve – wide receivers DJ Chark Jr. (hamstring), wide receiver Chris Conley (hamstring), cornerback D.J. Hayden (hip/wrist), safety Ronnie Harrison (eye), center Brandon Linder (shoulder), defensive end Calais Campbell (back) and left tackle Cam Robinson (knee) – also were removed and are expected to play Sunday. …
