Early Life and Background
Marshawn Kneeland was born on July 8, 2001, in Grand Rapids, Michigan, where he grew up before attending Godwin Heights High School in nearby Wyoming, Michigan. At Godwin Heights, he played both linebacker and tight end, showcasing the versatility that would later define his defensive career. As a senior, he recorded 110 tackles and eight sacks on defense while also contributing 20 receptions for 330 yards and five touchdowns on offense, demonstrating rare two-way ability for a high school player.
Although he was not heavily recruited out of high school, Kneeland committed to Western Michigan University to continue his football career. His combination of size, athleticism, and production drew attention even before he arrived on campus, setting the stage for his development into a professional prospect. He later resided in Plano, Texas, while playing for the Cowboys.
Path to American Football
Kneeland’s path to professional football began at Western Michigan University, where he played for the Broncos from 2019 through 2023. Over the course of his five college seasons, he developed from an under-recruited high school player into a reliable edge defender. His career totals at Western Michigan included 149 tackles and 12.5 sacks, along with three pass deflections and three forced fumbles, numbers that reflected his growth as a disruptive defensive end.
His senior season proved to be his most productive, earning him second-team All-MAC recognition in 2023. That honor, combined with his overall body of work, helped him earn an invitation to the NFL Scouting Combine, where he showcased the size and athleticism that had defined his college career. Despite his late rise as a prospect, Kneeland’s performance at the Combine and during his senior year positioned him as a desirable NFL talent heading into the 2024 draft.

He redshirted his first year before working his way into a larger role along the Broncos’ defensive front.

His second-team All-MAC selection in 2023 served as the capstone of his college development and helped pave the way for his transition to the professional level.
NFL Breakthrough (2024 Season)
Marshawn Kneeland was selected 56th overall in the second round of the 2024 NFL draft by the Dallas Cowboys, a significant moment for a player who had entered college as a lightly recruited prospect.

Over the course of the season, he appeared in 11 games and made one start, recording 17 tackles, two tackles for loss, 13 quarterback pressures, one pass breakup, and one fumble recovery.
His first career start came on October 6, 2024, against the Pittsburgh Steelers, a game in which he collected two tackles before leaving with a right knee injury sustained while attempting to sack quarterback Justin Fields. The injury required arthroscopic surgery and forced him to miss five weeks on injured reserve, cutting short what had been a promising rookie debut. Despite the setback, his first season established him as a rotational piece in the Cowboys’ defensive front.
Dallas Cowboys Era (2025 Season)
Entering the 2025 season, Kneeland was positioned for a larger role with the Cowboys following the departure of veteran DeMarcus Lawrence in free agency. He was viewed as a primary rotational player behind Dante Fowler, and during training camp he was considered a possible breakout candidate, highlighted by a clip of him intercepting quarterback Dak Prescott that circulated on social media.
In early October, Kneeland was added to the injury report with an ankle injury suffered during practice, an issue he later aggravated in a Week 6 game against the Carolina Panthers. Three days before his death, he scored his only NFL touchdown by recovering a blocked punt in the end zone against the Arizona Cardinals in Week 9. He appeared in seven games during the 2025 season, posting 12 tackles, one sack, and three quarterback pressures.

He was developing into a reliable rotational piece whose effort and toughness earned him respect within the Cowboys’ locker room.
Notable Events and Milestones
Among the most memorable moments of Kneeland’s professional career was his second-round selection in the 2024 NFL draft and his Week 9 touchdown against the Arizona Cardinals in 2025, when he recovered a blocked punt in the end zone for his only NFL score.
