Tragedy struck the Dallas Cowboys Wednesday night. Marshawn Kneeland, a rotational edge rusher who'd been a second-round draft pick in 2024, died. He was 24 years old.

The former two-star recruit built himself into a rising college football star at Western Michigan. He notched 25 sacks over his final three seasons in the Mid-American Conference to present the NFL with a high-upside prospect at one of the game's most valuable positions. While he was a project, he'd begun to work his way into a larger role for a needy Cowboys defense. He'd started three games in 2025, notching his first career sack in Dallas' season opener against the Philadelphia Eagles.

His biggest moment as a pro, however, came in what turned out to be the final game he'd ever play.

Sam Williams' blocked punt bounced into Kneeland's bread basket. From there, the 265-pound defender showed off his 4.7-second 40 speed in a sprint to the end zone. It was the only touchdown of his pro career and first since a 2023 rushing touchdown with the Broncos.

What was Marshawn Kneeland's cause of death?

Kneeland's cause of death has not been reported. His agent discussed his passing in a statement.

"I am shattered to confirm that my client and dearest friend Marshawn Kneeland passed away last night. I watched him fight his way from a hopeful kid at Western Michigan with a dream to being a respected professional for the Dallas Cowboys. Marshawn poured his heart into every snap, every practice, and every moment on the field. To lose someone with his talent, spirit, and goodness is a pain I can hardly put into words," said Johnathan Perzley.

"My heart aches for his family, his teammates, and everyone who loved him, and I hope they feel the support of the entire football community during this unimaginable time. I ask that you please give his loved ones the privacy and compassion they need as they grieve this tremendous loss."
