James Develin's career is finished.
The Patriots fullback surprisingly announced his retirement Monday with a post on Instagram.
"Due to unforeseen complications with the injury that ended my season last year, I have decided it is both in my and my family's best interest to retire from the game of football," Develin wrote. "I've always maintained a belief that in the sport, the team is MUCH more important than myself as an individual ... and that belief still rings true, as I have to prioritize my team at home before anything else."
Develin's neck injury cut his 2019 season short after just two games, which undoubtedly contributed to New England's ground-game struggles experienced in the latter portion of the season. The fullback known best for clearing running lanes for a number of Patriots backs finishes his time in the NFL with 83 games played from 2012-2019, including a run of five straight seasons in which he appeared in every regular-season game.
He wasn't much of a weapon with the ball in his hands, but Develin was a key to New England's offensive success throughout his career. His contributions will be missed by a Patriots team that is also taking its first steps into life without Brady.
The Patriots also announced that they have released defensive lineman Keointa Davis and defensive back Obi Melifonwu.
