The Detroit Lions’ margin for error keeps shrinking, and Thursday’s updated Week 16 injury report didn’t help matters.
Detroit added starting center Graham Glasgow to the report with a knee issue, immediately raising concern ahead of Sunday’s must-win matchup at Ford Field. Glasgow was not listed on Wednesday, making his sudden DNP (Did Not Practice) a notable and worrying development for an offense that can’t afford more disruption up front.
The Lions already entered the week juggling multiple injuries on both sides of the ball. Now, the status of their starting center becomes one of the biggest storylines heading into the weekend.

Why Graham Glasgow’s Status Matters
Glasgow has been a stabilizing force along the interior offensive line, and his absence would ripple quickly through Detroit’s offense. With the Lions needing a near-perfect performance offensively to stay in the playoff hunt, losing their center, even temporarily, would be a tough blow.
Detroit has already leaned on offensive line rotations recently, and while depth players have held up admirably at times, continuity remains critical in a high-stakes Week 16 game.

| Graham Glasgow | C | Knee | Not listed | NP | — | — |

Mixed Signals Elsewhere on the Report
While Glasgow’s addition is the headline, there are at least a few positives:
- Taylor Decker improved from NP to LP, a good sign for Detroit’s left tackle situation.
- Christian Mahogany and Thomas Harper both logged full practices, putting them on track for availability.
- Sione Vaki progressed to a full participant after starting the week limited.
However, Kerby Joseph remaining out for a second straight day continues to loom large for a secondary that’s already been stretched thin.
The Bottom Line
Adding Graham Glasgow this late in the week is not what the Lions needed, especially with everything on the line in Week 16. Detroit will be watching Friday’s practice closely to see if its starting center can bounce back quickly.
With playoff hopes hanging in the balance, every rep, every health update, and every lineup decision suddenly feels magnified.
