Dallas Cowboys defensive end Marshawn Kneeland has died at just 24 years old, the team announced. Kneeland was drafted in the second round in 2024 and played 11 games in his rookie season. He had already appeared in seven games this year, with his final appearance coming on November 6 against the Arizona Cardinals—where he scored his first NFL touchdown.

The Cowboys shared the tragic news in a statement expressing “extreme sadness,” calling Kneeland a beloved teammate. They also extended thoughts and prayers to his girlfriend, Catalina, and his family. The NFL echoed the sentiment, saying it was deeply saddened and offering support and counseling resources to the team.

No cause of death has been released. Kneeland, known for his strength and dedication, had overcome a knee injury early in his rookie year and was praised by coaches for his work ethic. Defensive coordinator Mike Zimmer previously said the young player was improving rapidly and was “a worker” who would continue to grow.

Before joining the NFL, Kneeland starred at Western Michigan, where he was known as “freakishly athletic” and committed to improving his craft—often practicing alone with his playbook. His loss is felt deeply across the Cowboys organization and the football community, leaving behind a promising career gone far too soon.
