What happened: Frank Ragnow confirmed his retirement on June 12, 2026, ending a decorated career spent entirely with the Detroit Lions. The move forces a major reshuffle for an offensive line that is already shifting Penei Sewell to the left tackle spot.

Why it matters: While Detroit has stars at the skill positions, Ragnow was the intelligence behind a rushing attack that consistently ranked in the top five of the NFL. Replacing a perennial All-Pro at the center position is arguably the most difficult task for a contending team, especially given his role in pre-snap adjustments.
