Bears safety Eddie Jackson will be game-time decision vs. Eagles

Safety Eddie Jackson’s return from an injured right ankle is now a matter of finding his ‘‘X percent.’’ That’s how coach Matt Nagy views Jackson’s potential availability for the Bears’ playoff matchup Sunday against the Eagles.

‘‘The hard part is where he’s at,’’ Nagy said Friday. ‘‘OK, if he’s X percent, whatever that is, is that something that is smart for him? Is that smart for the team?’’

After being limited in practice for a second consecutive day, Jackson officially was listed as questionable for the game. Nagy called him a game-time decision.

‘‘He’s literally going to go right up to [the deadline],’’ Nagy said. ‘‘We’ll test him out, see how he is. He was able to get in there a little bit [Friday] and do some individual work and then jump in the practice in certain spots.’’

Jackson was one of four Bears named first-team All-Pro on Friday, joining outside linebacker Khalil Mack, cornerback Kyle Fuller and punt returner Tarik Cohen. But he’s also the most important of four players listed on the Bears’ injury report. Jackson hasn’t played since twisting his right ankle after making an interception against the Packers in Week 16.

Outside linebacker Aaron Lynch didn’t practice all week because of an injury to his right elbow and is listed as doubtful. Defensive tackle Bilal Nichols got another day off because of a nagging knee issue, but he’s expected to play. Backup safety/special-teamer DeAndre Houston-Carson has sore ribs and also got a day off. Nichols and Houston-Carson are listed as questionable.

As for Jackson, being in the postseason certainly affects his ‘‘X percent.’’

‘‘Probably slightly because it is win or go home,’’ Nagy said.

Deon Bush has played well in Jackson’s place, but the Bears’ defense is more formidable with Jackson in it. Jackson didn’t speak with the media Friday. The team said he was undergoing treatment.

‘‘The team and the player, you have to look at it from both sides, and that’s the hard part,’’ Nagy said. ‘‘We’ve all got to be honest and see exactly where he’s at. That’s the only thing you can do, and then you just keep rolling.’’

Jackson has nearly two full days to improve between the end of practice Friday and when inactives are due Sunday. All signs still point to his return.

‘‘We’re going to have no regrets,’’ Nagy said. ‘‘So if he goes in and he plays at X percent, then that’s it. And if he doesn’t play, then that’s the decision we made.’’
