The Detroit Lions injury report features several key names heading into Sunday’s matchup against the Pittsburgh Steelers, with two players officially ruled out and five others listed as questionable.
Graham Glasgow Questionable vs Steelers
The Lions have listed center Graham Glasgow as questionable due to a knee injury. Glasgow was absent from both Thursday and Friday practices after not appearing on Wednesday’s walkthrough injury report, raising concern about his availability.
If Glasgow is unable to play, Detroit does have options. Trystan Colon, who has started the last three games (one at center, two at left guard), could slide inside. Michael Niese and Kingsley Eguakun are also candidates at center.
Five Lions Listed as Questionable
Along with Glasgow, the Lions have four additional players listed as questionable:
Taylor Decker (LT) – shoulder/rest
Trystan Colon (IOL) – wrist
Christian Mahogany (G) – fibula
Amik Robertson (CB) – hand
Decker has played through his shoulder injury most of the season, appearing in eight straight games after missing two earlier in the year.
Mahogany, who has missed the last six games with a broken bone in his leg, has practiced for two weeks and is nearing a return. Head coach Dan Campbell said the decision will come down to how Mahogany responds physically.
Robertson has been limited in practice all week after injuring his hand while attempting a forced fumble against the Los Angeles Rams. Both the team and the player remain optimistic he’ll play, with Robertson considering wearing a protective club.
Lions Rule Out Kerby Joseph, Giovanni Manu
Detroit has officially ruled out:
Kerby Joseph (S) – knee
Giovanni Manu (OT) – knee
Joseph will miss his ninth straight game after suffering a setback during practice last week. His chances of returning before the end of the regular season are increasingly unlikely.
Manu recently had his 21-day return window opened, but Campbell indicated the move was more about development and offseason preparation for the rookie offensive tackle.
Steelers Injury Update: TJ Watt Out
On the Steelers’ side, TJ Watt has been ruled out due to a partially collapsed lung suffered during a dry-needling procedure. Watt also missed last week’s game and remains sidelined despite a strong season that includes seven sacks, 18 quarterback hits, and three forced fumbles.
Key Takeaway
The Lions enter a crucial matchup against the Steelers with uncertainty across the offensive line and secondary, while Pittsburgh will be without its top defensive star. Final injury designations could significantly impact Sunday’s game at Ford Field.
