Lions C Travis Swanson is in the concussion protocol.
It comes out of nowhere after Swanson played all 70 snaps in last week?s win.
The Lions will likely move Graham Glasgow inside if Swanson is held out, with Laken Tomlinson starting at guard.
Eric Ebron (knee) remained limited at Thursday's practice.
He's been dealing with knee issues off and on all season.
There's no concern about Ebron's status for Week 14.
Consider him a borderline TE1 for Sunday's tilt with Chicago.
Marvin Jones (quad) remained limited at Thursday's practice.
He sat out last week's game with a quad injury but has a much better chance to suit up Sunday against the Bears.
Jones hasn't scored a touchdown since Week 6 and won't be more than a back-end WR3 in Week 14.
Dwayne Washington (ankle) remained "limited" in Thursday's practice.
Washington is on track to suit up as the Lions' primary early-down back against the Bears.
With Washington at less than 100 percent, it's possible Zach Zenner gets more work than usual.
Theo Riddick (wrist) returned to a limited practice on Thursday.
He sat out with a wrist injury on Wednesday but was seen at the open portion of Thursday's session.
There's no concern about his status for Week 14. Riddick has settled in as a weekly RB3 in fantasy.
