Jaguars signed OL Paul McQuistan.
The former Raiders' bust is getting another shot after being waived on Nov. 9. He'll give the Jags some depth at both guard and tackle.
Jaguars released S Brian Russell.
Ruseell, 31, isn't even needed in the secondary with Rashean Mathis (groin) out.

Jaguars MLB Justin Durant is unlikely to play in Week 11 against the Bills after suffering a concussion in last week's win.
The injury wasn't revealed until Jack Del Rio's Wednesday post-practice news conference. Durant has been a solid IDP, averaging nearly nine tackles a game. His absence would slightly upgrade Marshawn Lynch's matchup.
In addition to CB Rashean Mathis (groin), the Jags may also be without MLB Justin Durant (concussion) and SS Gerald Alexander (shoulder) in Week 11.
The Bills offense may have a fighting chance this week even with Ryan Fitzpatrick under center. The Jags are talking about playing Reggie Nelson at corner again, which would be great news for Lee Evans in a highly favorable matchup.
Jags LB Russell Allen is expected to start in place of Justin Durant (concussion) this week.
Allen has reportedly impressed the Jags with his "mobility and tackling ability" as a reserve, but he's not on Durant's level. Updgrade the matchup for Marshawn Lynch, who is still just a RB2/flex with Fred Jackson eating into his workload.

Jaguars CB Rashean Mathis (groin) has been ruled out for Sunday's game against the Bills.
It's unclear exactly how long Mathis will be out, but it could be multiple games. When Mathis missed the Week 8 loss to the Titans with a finger injury, FS Reggie Nelson shifted to corner. We would say to upgrade the Bills passing game, but the arm of Ryan Fitzpatrick negates any advantage gained here.

With 123 yards Sunday, Maurice Jones-Drew became the first running back to top 100 rushing yards against a Rex Ryan defense since Larry Johnson accomplished the feat in 2006.
Much of that can be attributed to the loss of NT Kris Jenkins (ACL), but Jones-Drew is enjoying an excellent season. He leads the league with 12 touchdowns while averaging 120 yards per game and 5.1 yards per carry in his first stint as the Jags' every-down back.
