With Mathis out, Middleton on the spot

The Jaguars don’t have great outside cornerback depth.

In four games starter Derek Cox missed earlier this season, Jacksonville lost all four and gave up an extra 40 passing yards a game.

Now Cox’s counterpart, veteran cornerback Rashean Mathis, is lost for the remainder of the year with a torn ACL.

While the Jaguars have a nickel corner in Drew Coleman best suited for inside work, their options to replace Mathis outside are a significant drop-off: William Middleton played for Cox, and the other corners on the team are undrafted rookies T.J. Heath and Kevin Rutland.

“(Middleton) did a solid job finishing the game for us,” Jack Del Rio said. “We’ve got some other young players and I know that Gene (Smith) is busy trying to acquire a player. I’m sure before the day’s out or by tomorrow we’ll have somebody at that spot...”

“The task for all of us on this team is to know your role and make sure you take care of your assignment and do your job within the confines of what the football team is asking you to do. So that doesn’t really change for Will.”

The Jaguars also put offensive lineman Eben Britton, who’s enduring complications from back surgery, and linebacker Kyle Bosworth (hand) on IR.

They signed tight end Fendi Onobun from the Redskins’ practice squad. They still have two open roster spots.
