The Florida Times Union expects Russell Allen to challenge Clint Session for the Jaguars' starting weak-side linebacker job.

Allen is at worst the Jaguars' top backup at all three linebacker positions, and he held his own in six spot starts last season. With a new coaching staff in Jacksonville, Session's $29 million contract no longer carries as much weight in camp battles. Session was concussed three times last year.

Jaguars agreed to terms with LB Russell Allen on a three-year contract.

A restricted free agent, Allen was tendered at the second-round level just prior to agreeing on the new deal. The Jaguars value Allen highly after he held his own while filling in for Phillip Wheeler late last season. Allen will return to a reserve/special teams role in 2012.

The Jaguars are attempting to work out a multi-year deal with restricted free agent LB Russell Allen.

Allen has appeared in all 48 games since signing as an undrafted free agent in 2009, making 15 starts. He played 293 snaps in 2011, grading out positively against the run and in coverage by Pro Football Focus.

Russell Allen is expected to replace Clint Session (injured reserve, concussions) in the starting lineup.

Allen, a former undrafted free agent, will step in on the weak side. He started four games at outside linebacker last season, piling up 42 tackles.
