Cowboys Defensive End Did Not Participate Today After Donating Bl00d to Save His Mother’s Heart Valve Surgery

Arlington, TX – The Dallas Cowboys opened practice this week missing one of their young defensive linemen, but his absence had nothing to do with football. Instead, it was about family, sacrifice, and a moment that transcended the game.

According to team sources, a second-year edge rusher was excused from drills after donating blood earlier this week to support his mother during a heart valve replacement surgery. The Cowboys listed him as

Did Not Participate, but emphasized that his priorities were exactly where they needed to be.

That player is Marshawn Kneeland, a defensive end drafted in the second round (No. 56 overall) out of Western Michigan in 2024. In his second season, Kneeland has carved out a meaningful role in Dan Quinn’s rotation, showing flashes of the disruptive potential Dallas envisioned when they picked him.

Through the first four games of the 2025 season, Kneeland has logged 8 combined tackles (4 solo, 4 assists), along with 1.0 sack for 8 yards in Week 1 vs. the Eagles

. He’s also credited with 3 quarterback pressures, ranking fifth on the team behind Sam Williams (5), Dante Fowler (4), Osa Odighizuwa (4), and Kenny Clark (3), per team reports.

While he has yet to force a fumble or snag an interception, Kneeland’s consistent presence off the edge has been valuable for a defensive front still adjusting after major roster changes. His development remains a key storyline for Dallas in 2025.

Head coach Mike McCarthy spoke highly of the young defender’s choice: “What Marshawn did for his mother says everything about who he is. Football is important, but moments like these remind us what really matters. We support him fully.”

Cowboys fans, who have already praised Kneeland’s growth from promising rookie to steady contributor, responded with an outpouring of support on social media. For many, the gesture was another sign that he embodies the toughness and loyalty they expect in a Cowboy.

While his absence today was noted on the practice report, Kneeland is expected back soon. And when he returns, he’ll carry with him not just the hunger to pressure quarterbacks, but also the strength of a son who put family first.
