C.J. Mosley, the five-time Pro Bowl linebacker, has officially announced his retirement from the NFL at the age of 33. The announcement coincided with his birthday and was shared through a highlight reel on his Instagram account. After being released by the New York Jets in March, Mosley had been without a team, marking the end of a notable career in which he served as an emotional leader and key defender for the Jets. Injuries plagued his recent seasons, including a significant absence from 13 games last year due to toe and neck issues, which ultimately played a role in his decision to retire.
