The Detroit Lions remain optimistic about running back David Montgomery's potential return from what was initially thought to be a season-ending knee injury. Coach Dan Campbell indicated that they are awaiting further medical opinions before making any decisions regarding his status.

Meanwhile, the Lions have placed several players, including Alim McNeill and Carlton Davis, on injured reserve, bringing their total to an NFL-high 21. In response, they've signed linebacker Anthony Pittman and cornerback Stantley Thomas-Oliver to bolster their roster as they prepare for a crucial matchup against the Chicago Bears.
