The Chicago Bears secondary has been arguably the best in the NFL through five weeks. They rank sixth in passing defense (174 passing yards per game) and have allowed just two passing touchdowns all season and an opponent average passer rating of 68.2 (best in NFL).

Ahead of Sunday's matchup against the Jacksonville Jaguars, the Bears are dealing with some injuries to the secondary. Safety Jaquan Brisker suffered a concussion in last week's win, and he's already been ruled out, which is a huge blow. Unfortunately, Brisker isn't the only one dealing with an injury.

Cornerback Tyrique Stevenson suffered a calf injury during Thursday's practice, and he's officially doubtful against the Jaguars. Head coach Matt Eberflus told reporters the Bears will see Saturday whether Stevenson will be healthy enough to go through a pre-game warmup to determine if he might be able to play.

If Stevenson can't go, which appears to be the indication, it'll likely be Jaylon Jones getting the starting nod on the outside opposite Jaylon Johnson.

"He knows (the defense) in and out," Eberflus said of Jones.

Jones has only played nine coverage snaps this season (where he has two pass breakups on two targets), but, for what it's worth, he's the highest-graded cornerback in the NFL at 91.9 this season.
