A nightmare-inducing season for the Chicago Bears has brought more frightening news to coach John Fox.

Jay Cutler is undergoing tests for a shoulder injury sustained in Sunday's loss to the New York Giants, NFL Network's Ian Rapoport reported, via a source informed of the injury. The starting quarterback is expected to miss time, per Rapoport. The team will know more Tuesday, with one source acknowledging the possibility that the injury could be serious in nature.

The Chicago Tribune first reported the development.

As NFL Network's Mike Garafolo pointed out, Fox told reporters there were severals reasons Cutler couldn't take advantage of the Giants' defense stacking the box. A shoulder issue would certainly qualify as one of those factors. This is Cutler's second injury of the season. He missed five games in September and October with a sprained thumb. The Bears have already lost quarterbacks Connor Shaw (broken leg) and Brian Hoyer (broken arm) to major injuries, leaving journeyman third-stringer Matt Barkley as the lone in-house replacement for Cutler.

Bears QB Brian Hoyer has a broken left arm. Packers RB Don Jackson has suffered a hand injury.

Matt Barkley relieved Hoyer, but this injury to Hoyer might accelerate Jay Cutler's rehab. The Packers are down to one healthy running back (Knile Davis) and WR-turned-RB Ty Montgomery, who looked good on Thursday night.

There wasn't a lot of doubt both RB David Johnson (toe) and WR John Brown (shoulder) would play in this NFC final today. Both are active and ready to go.

Michael Floyd is active vs. the Seahawks after a questionable tag this week with a knee issue. It's a tough matchup, but Floyd has over 70 receiving yards his last four games including three, 100-yard-plus games in that span.

Michael Floyd (hamstring) is active in a very good matchup against the 49ers. Floyd was starting to put things together before missing last week's game.

Michael Floyd is out for SNF with a hamstring injury. Floyd has been a nice play of late, but with him out John Brown - who is active despite a hamstring issue - should be more involved in the offense, as could Jaron Brown.
