David Montgomery leaves Titans game with a groin injury

Texans running back David Montgomery left Sunday's game at Tennessee with a groin injury. Houston announced on its official account that he is questionable to return, and Ian Rapoport of NFL Network relayed the same update moments later.

What is confirmed

The Texans called it a groin injury and listed Montgomery as questionable to return. That is the full extent of the official word so far.

Houston led 9-3 late in the second quarter when we checked the ESPN scoreboard.

What is reported

Aaron Wilson of KPRC 2 wrote that Montgomery walked to the locker room for further examination. Wilson also noted that the injury leaves Woody Marks and Dare Ogunbowale as Houston's only healthy active running backs.

Before he went down, Montgomery had five carries for 11 yards, per Wilson. Marks had four carries for 19 yards.

Groin injuries vary widely. Some players return the same day, while others miss a week or more. There is no timeline yet.

Why it matters for RSO rosters

Montgomery has been the lead back in Houston, but his early production today was thin. If he stays out, Marks takes over the early-down work for the rest of the afternoon, with Ogunbowale behind him.

For dynasty and contract leagues, the bigger question is whether a missed week opens the door for Marks to earn a larger share going forward.

What to do now

Hold Montgomery for now. Do not cut or dump him off one in-game report.

If Marks is on your waiver wire, he is the add to make before the week's claims process. If you already roster him, keep him close to your lineup for Week 6.

Watch for the Texans' postgame injury update and the first practice report of the week. A did-not-practice line on Wednesday and Thursday would put Montgomery's Week 6 status in doubt and make Marks a likely starter.
