The Lions won’t have two key players for Thursday’s game against the Bears, but two other players are trending in the right direction.

Offensive tackle Taylor Decker (knee) and cornerback Carlton Davis (knee/thumb) are out. But running back David Montgomery (shoulder) and receiver Amon-Ra St. Brown (knee) are both questionable.

Decker and Davis were listed as non-participants on all three injury reports from the short week.

Montgomery and St. Brown were both listed as full participants on Wednesday. They were limited on Tuesday and DNPs on Monday.

Montgomery and head coach Dan Campbell both said Montgomery wanted to return to the game in last week’s win over the Colts, but the club stopped him out of precaution.

Cornerback Terrion Arnold (groin) and defensive lineman DJ Reader (illness) are both off the injury report and will play. Arnold and Reader were both full participants in the reports on Tuesday and Wednesday.

Additionally, the Lions announced the previously reported move to place receiver/returner Kalif Raymond (foot) on injured reserve. He will be out for at least four weeks.

Receiver Maurice Alexander and linebacker David Long were signed to the 53-man roster from the team’s practice squad.

Offensive lineman Jamarco Jones was called up to the gameday squad from the practice squad.
