The Chicago Bears won the NFC North division title on the strength of their defense, but they might have to go into their Wild Card Round matchup against the Philadelphia Eagles this Sunday without one of their best defensive players.

According to Mike Florio of Pro Football Talk, safety Eddie Jackson remained out of Bears practice on Wednesday due to an ankle injury he suffered during Chicago's division-clinching win over the Green Bay Packers two weeks ago.

This is obviously not great news for the Bears, as Jackson is so integral to what Chicago does defensively.

The second-year defensive back racked up 51 tackles, a sack, six interceptions, two forced fumbles, a fumble recovery, three defensive touchdowns and 15 passes defended this year en route to his first Pro Bowl selection.

Jackson, who played his collegiate football at the University of Alabama, was originally selected by the Bears in the fourth round (112th pick overall) of the 2017 NFL Draft.

He had an impressive rookie campaign, playing in all 16 games and finishing with 70 stops, two picks, a forced fumble, three fumble recoveries, two defensive touchdowns and six passes defended.

Obviously, Jackson has a nose for the end zone, as he has already racked up five touchdowns in just two seasons.

The good news for Chicago is that wide receiver Allen Robinson, who missed the Bears' season finale against the Minnesota Vikings with a rib injury, was a full participant in practice on Wednesday, as were fellow wideouts Taylor Gabriel (ribs) and Anthony Miller (shoulder).
