Frank Ragnow fails physical, will not rejoin Lions after attempting to end retirement

Frank Ragnow's attempt to return to the Detroit Lions has ended after he failed a physical examination. The four-time Pro Bowl center, who retired in June following a seven-year career, was found to have a Grade 3 hamstring strain. This injury will prevent him from participating for the rest of the regular season, as announced by the team. The Lions, who moved Graham Glasgow from guard to center after Ragnow's initial retirement, have been dealing with injuries across their offensive line. Ragnow's attempted return was seen as a potential boost for the Lions, who are currently 7-5 and facing challenges in maintaining a winning streak.
