David Montgomery Ruled Out vs. Jaguars in London with Groin Injury

David Montgomery has been ruled out for Houston's Week 6 game against the Jaguars in London with a groin injury, confirmed by the team's official injury report. The injury date is confirmed as October 11, 2026, placing Montgomery four days into what is most commonly a soft-tissue groin or adductor complex injury.

"Groin injury" in the NFL covers a wide spectrum — from a straightforward adductor or hip flexor strain to athletic pubalgia (the entity often mislabeled "sports hernia"), which involves the posterior inguinal wall musculotendinous complex and carries a materially different recovery trajectory. The grade is INFERRED from the available reporting: ruled out for one game at four days post-injury is consistent with a Grade 1–2 myotendinous strain. A Grade 1 adductor strain typically resolves in one to two weeks; a Grade 2 strain runs three to five weeks. If this is athletic pubalgia — more likely in a workhorse back with chronic groin loading — the timeline extends considerably and conservative management has a poor long-term track record, with many cases ultimately requiring surgical repair (8–12 weeks post-op).

Montgomery is now four days out from the confirmed injury date. The team's "Out" designation is an availability label, not a timeline, and carries no week count. At this stage the most probable diagnosis is a Grade 1–2 myotendinous groin strain, with the lower end of that window suggesting he could be in play as early as Week 7, though any residual pain or functional limitation at a high-speed cutting position like RB warrants genuine caution about compressing the timeline. The key watch signal is whether this reappears on next week's injury report and whether the team provides any clarifying language about the nature of the injury — "groin" covering athletic pubalgia is a meaningful clinical distinction that would substantially shift the RTP window.
