Chicago Bears rookie quarterback Justin Fields is nursing an ankle injury, and has been officially listed as questionable to play vs. the Seattle Seahawks on Sunday. He was a limited participant in practice Wednesday but sat out Thursday and Friday. In fact, head coach Matt Nagy has already ruled out him starting, and will instead put Nick Foles under center in Week 16, per Ian Rapoport of the NFL Network

Andy Dalton would usually be the second-string quarterback, but he has been ruled out with a groin injury. Fields may still be active this week, although it will be in a backup/emergency role. He completed 26 of 39 passes for 285 yards and one touchdown in the 17-9 loss to the Minnesota Vikings on Monday night.

Foles hasn't played a down for the Bears this season. Last year, he completed 202 of 312 passes for 1,852 yards, 10 touchdowns and eight interceptions while going 2-5 as the starter. The Philadelphia Eagles legend has spent the past two years with the Jacksonville Jaguars and the Bears while going a total of 2-9 as a starter. 

It's a curious move, as Fields appears to be a legitimate game-time decision. The Bears are 4-10 and have officially been eliminated from the playoffs. It will be interesting to see if Foles will be able to find some level of relative success against the second-worst defense in the NFL
