David Montgomery, running back for the Detroit Lions, is expected to miss some time due to a rib cartilage issue. In Sunday's game against the Bucs, Montgomery played just 18 snaps before leaving with the injury. On the season, he has rushed 94 times for 385 yards and six touchdowns, with six catches for 66 yards as a receiver. In his likely absence in Week 7, the Lions will look to get Jahmyr Gibbs back from his hamstring injury and rely more on Craig Reynolds.
