Linebacker Paul Posluszny misses practice

JACKSONVILLE, Fla. -- Jacksonville Jaguars middle linebacker Paul Posluszny missed his third consecutive practice with a concussion, but coach Gus Bradley said there’s still a chance Posluszny could play in Sunday’s game against Arizona.

Bradley also said starting left guard Will Rackley is doubtful because of a concussion. Reserve receivers Stephen Burton (concussion) and Stephen Williams (Achilles) are out.

But it’s potentially not having Posluszny that hurts the most. He is the team’s best defensive player and responsible for three of the defense’s 12 turnovers. He has a team-high 88 tackles, two interceptions, eight pass breakups, two forced fumbles, and one fumble recovery.

"We’ll see how Paul feels in the morning," Bradley said. "We still have tomorrow morning to evaluate it and see where he’s at."

Posluszny, who suffered the concussion in the fourth quarter of the Jaguars’ 29-27 victory against Tennessee last Sunday, did not practice all week.

Outside linebacker Russell Allen, who has started 39 games in his five seasons, will start in place of Posluszny. Allen set career highs in tackles (201) and pass breakups (eight) in 2012, and has 40 tackles and two fumble recoveries.

"Fortunately we’ve had all week of practice with Russell in there and he’s done a nice job this whole week," Bradley said. "He was thrown into a little tougher situation last week with the limited amount of reps, so at least this week he got multiple reps.

"That’s where Russell’s so important to us -- in other ways, too -- but the flexibility to play multiple positions."

Rackley missed last week’s game with a concussion suffered against San Francisco on Oct. 27. He was limited in practice on Wednesday and Thursday, but did not practice Friday.
