In a surprising turn of events, Detroit Lions defensive lineman John Cominsky has announced his retirement from the NFL at the age of 29. The decision, which he revealed through an Instagram post, comes as a result of medical concerns following a severe knee injury. Cominsky, a respected player known for his toughness and work ethic, cited accumulated injuries and the toll they have taken on his body as the primary reasons for stepping away from the game.
Cominsky’s NFL journey began when he was selected in the fourth round of the 2019 NFL Draft by the Atlanta Falcons. The defensive lineman played three
2019 NFL Draft by the Atlanta Falcons. The defensive lineman played three seasons with the Falcons before being waived in May 2022. Shortly thereafter, the Detroit Lions claimed him off waivers, a move that would prove beneficial for both Cominsky and the team. In Detroit, he quickly established himself as a valuable contributor to the Lions’ defensive front, earning a two-year contract extension in March 2023 after a strong 2022 campaign.

Unfortunately, Cominsky’s 2024 season was derailed before it even began. During training camp, he suffered a torn MCL, an injury that forced him onto the injured reserve list for the entire season. Despite months of rehabilitation and an effort to make a full recovery, Cominsky ultimately decided that the risk of further injury outweighed his desire to continue playing. His announcement marks the end of a six-year NFL career filled with perseverance, hard work, and a commitment to excellence.
Lions head coach Dan Campbell spoke highly of Cominsky following his retirement announcement, praising his dedication to the team and the game. “John gave everything he had every time he stepped on the field. His toughness and leadership were instrumental in what we’ve built here in Detroit,” Campbell said. “It’s unfortunate that injuries played a role in cutting his career short, but he has nothing to hang his head about. We’re grateful for everything he brought to this team.”
Cominsky’s impact on the Lions extended beyond the stat sheet. His leadership in the locker room and relentless energy on the field made him a fan favorite in Detroit. Over the course of his career, he appeared in 50 games, recording 107 total tackles, 7.5 sacks, and six passes defended. While those numbers may not jump off the page, his contributions to the Lions’ defensive success were undeniable.
For Cominsky, retirement represents a new chapter in his life. While he did not specify his future plans in his retirement statement, many speculate that he could transition into coaching, player development, or media work. Given his deep understanding of the game and the respect he commands from teammates and coaches alike, he has several potential avenues to explore in the football world.
As the Lions prepare for the 2025 season, they will need to fill the void left by Cominsky’s departure. His presence will be missed both on and off the field, but his contributions to the team’s culture and success will not be forgotten. Fans, teammates, and coaches alike have expressed their gratitude for his time in Detroit and wished him the best in his post-football endeavors.
