For the first time since Detroit Lions center Frank Ragnow announced his retirement at 29, coach Dan Campbell spoke with the media. Campbell spoke glowingly of Ragnow's contributions to the team and revealed the decision didn't exactly catch the team off guard.

After a few months of clarity and consideration, Frank Ragnow — the All-Pro center who anchored one of the league’s best offensive lines — is calling it quits. In the end, Ragnow, 29, is prioritizing his long-term health. His seven-year career saw him play through injury after injury in an effort to help a losing franchise become a winner.
