If Montgomery opted to undergo surgery, something Lions coach Dan Campbell said Monday was happening, the veteran running back would miss the rest of the season, including the playoffs. If he opts to let the injury scar over and heal naturally, he could return at some point in the postseason.

He eventually limped off after staying in to block on a fourth-down conversion on Detroit's second touchdown drive. Montgomery returned and had five touches in the second half, but primarily sat in favor of fellow starting running back Jahmyr Gibbs.

Lions coach Dan Campbell offered the latest injury news on Graham Glasgow, Alex Anzalone, and Jalen Reeves-Maybin.
