Eight months removed from a concussion that ended his 2011 season, Jacksonville Jaguars linebacker Clint Session's playing future is in question as the 27-year-old opened training camp on the physically unable to perform list (PUP) because of post-concussion symptoms, head coach Mike Mularkey said on Friday.

"It's definitely a concern," Mularkey said, according to Gene Frenette of The Florida Times-Union. "We don't know the future with him."
In nine games, Session totaled 30 tackles and a sack before being placed on injured reserve. Session's contract included more than $11 million in guaranteed money, including a $2 million roster bonus he received in March and a $1.9 million base salary for the upcoming season.
While Session is out, the Jaguars will use Russell Allen at weakside linebacker. A core special teams player, Allen finished the 2011 season in the starting lineup, posting 34 tackles and a half-sack in the final seven weeks of the season. The Jaguars signed Allen to a three-year, $6 million contract in March.
