Lions coach Dan Campbell said Tuesday that he's optimistic that Montgomery (thigh) will be able to play in Thursday's game versus the Packers.
Montgomery missed Week 3 due to a thigh bruise but was listed as a limited participant on Monday's estimated practice report. His return would likely mean less usage for rookie first-round pick Jahmyr Gibbs, who saw 17 rushing attempts versus Atlanta after garnering just 14 through the first two weeks of the season.
