Jaguars LB Paul Posluszny won't play vs. Bears due to bruised biceps


JACKSONVILLE, Fla. -- Jacksonville Jaguars linebacker Paul Posluszny won't play at Chicago on Thursday night because of a bruised biceps.
The team says Posluszny will remain in Jacksonville for treatment and could be back at practice soon.
Second-year player Nate Stupar is expected to start in Posluszny's place against the Bears.
Posluszny has led the team in tackles the last three years, including a career-best 231 in 2012. He ranked second in the NFL with 161 tackles last season.
Posluszny's absence means the Jaguars will be without two starting linebackers in their second preseason game. Dekoda Watson, signed in free agency to replace Russell Allen, is on the physically unable to perform list while he recovers from groin surgery.
In other team news, the Jaguars signed veteran center Antoine Caldwell and waived/injured center Matt Stankiewitch.
Stankiewitch has a wrist injury and will revert to the team's injured reserve if he clears waivers.
Caldwell spent two days with the Jaguars in May, trying out for the team during a rookie minicamp. The 6-foot-3, 315-pound Caldwell was a third-round draft pick by Houston in 2009. He played in 39 games with 19 starts. He spent parts of the 2013 preseason with Buffalo before being released in final cuts.
The former Alabama standout was a first-team All-America selection as a senior in 2008. He was a four-year starter for the Crimson Tide, seeing action at guard and center.
Jaguars center Mike Brewster struggled in the team's preseason opener, airing two shotgun snaps over quarterback Chad Henne's head.
