With Session done, Allen steps in for Jags

Russell Allen is a capable linebacker who should thrive playing with Daryl Smith and Paul Posluszny the rest of the way for the Jaguars.

But Allen is simply not as dynamic or as impactful as the guy he’s replacing, Clint Session.

The Jaguars put Session on IR after he suffered his second concussion of the season Sunday in Cleveland.

It’s a disappointing end to the year for the big-hitting linebacker, who joined the Jaguars as a free agent from Indianapolis before the season. He arrived with a bit of a reputation for getting banged up, and it’s unfortunate he’s adding to that.

Allen made the Jaguars in 2009 as an undrafted free agent from San Diego State.

The challenge for him is to do his part without trying to be Session. Posluszny and Smith are outstanding players having good seasons for a defense that’s had to carry Jacksonville this season.

Sunday the Jaguars hope to disrupt Matt Leinart in his first start in place of Matt Schaub, the Houston Texans quarterback who’s out with a serious foot injury.

Here is Scouts Inc.’s report on Allen:

"Allen is an active linebacker with a good nose for the ball. He is quick to locate the ball and takes good angles to get to the play. He has adequate lateral range and shows good effort to get to the perimeter and make plays near the sideline. He can struggle when stepping up into the hole and trying to take on blockers and leverage his way to the play, but he generally does a good job of playing the edges and slipping blocks. He is most effective when he is protected up front and left free to run and make plays. He gets good depth in his drops and shows improving route recognition."
