Lions running back David Montgomery suffers rib injury in first half vs. Buccaneers

The Detroit Lions were thin at running back for Sunday's game against the Tampa Bay Buccaneers, with Jahmyr Gibbs (hamstring) missing his second straight game and Zonovan Knight (left shoulder) going on IR) after being injured in Week 5

The Lions struggled to get much going on the ground in the first half of Sunday's game, against a tough Tampa Bay run defense. David Montgomery got loose on a screen for 19 yards in the second quarter, but he landed hard on his left side and left the game. He was able to walk to the sideline under his own power, however slowly after being down on the field for long enough to cause concern.

So it didn't appear to be a lower body issue for Montgomery, so a worst-case scenario appears to have been avoided. FOX sideline reporter Pam Oliver said a cart came to take Montgomery to the locker room, but he waved it off and he was seen walking to the locker room (presumably for further testing/x-rays).

David Montgomery injury update: Will he re-enter Sunday's game?

An update came on Montgomery pretty quickly-a rib injury, and he's questionable to return.

Craig Reynolds replaced Montgomery in the game. His highlight of the first half was a crushing block on Amon-Ra St. Brown's touchdown reception.

Devine Ozigbo was elevated from the practice squad as the corresponding move to Knight going on IR. So it's he and Reynolds for the rest of Sunday's game as the Lions only healthy running backs, unless Montgomery is able to return.

Montgomery has been an essential part of the Lions' offense so far this season, with six touchdowns in the four games he had played before Sunday (he missed Week 3 with a thigh bruise). Coming out of halftime Oliver reported, upon having talked to head coach Dan Campbell, that x-rays on Montgomery came back negative. So he may be facing an extended absence, but it seems somewhat unlikely he'll return to Sunday's contest.

Update: Montgomery has been ruled out for the rest of Sunday's game.
