Marshawn Kneeland Cause of Death

Marshawn Kneeland died at 24 on November 6, 2025, after Frisco police found him following a vehicle pursuit and crash in Frisco, Texas. Police initially reported an apparent self-inflicted gunshot wound and said the medical examiner would determine the cause and manner of death. In July 2026, the Concussion & CTE Foundation said Kneeland died by suicide and announced that a postmortem examination had also found Stage 1 chronic traumatic encephalopathy (CTE).

Key Facts

The timeline matters when reading these facts. Frisco police initially described an apparent self-inflicted gunshot wound and said the medical examiner would determine the cause and manner of death. Months later, the Concussion & CTE Foundation publicly stated that Kneeland died by suicide and announced the Stage 1 CTE diagnosis.

What Happened to Marshawn Kneeland?

Marshawn Kneeland died during the early morning hours of November 6, 2025, in Frisco, Texas. The Frisco Police Department became involved after receiving information about Kneeland and later pursuing a vehicle connected to the incident.

The vehicle crashed, and Kneeland then left the vehicle on foot. Officers searched the area and found him at about 1:31 a.m. with an apparent self-inflicted gunshot wound, according to the police department’s initial statement.

Police also said they had received information that Kneeland had expressed suicidal ideation. At that stage, investigators had not completed the death investigation and said the Collin County Medical Examiner would determine the official cause and manner of death.

When Did Marshawn Kneeland Die?

Marshawn Kneeland died on November 6, 2025, in Frisco, Texas. He was 24 years old.

The Dallas Cowboys confirmed his death that day. Kneeland had been in his second NFL season and had played for Dallas just three days earlier against the Arizona Cardinals.

That game became the final appearance of his professional career. It also produced his first NFL touchdown.

Did Marshawn Kneeland Die by Suicide?

Yes. The Concussion & CTE Foundation stated in July 2026 that Marshawn Kneeland died by suicide at age 24. The organization released that information while announcing the results of a postmortem examination of his brain tissue.

Frisco police had reported the previous November that Kneeland had suffered an apparent self-inflicted gunshot wound. Police initially left the cause and manner of death to the medical examiner as the investigation continued.

The public record therefore developed in two stages: the initial police account described the circumstances surrounding his death, while the later Foundation statement explicitly described the death as suicide.

Did CTE Cause Marshawn Kneeland’s Death?

The available evidence does not establish that Stage 1 CTE caused Kneeland’s suicide.

Researchers have cautioned against making that connection from a postmortem CTE diagnosis alone. Christopher Nowinski, a researcher and co-founder of the Concussion Legacy Foundation, said that suicide involves complex and multiple factors and that Stage 1 CTE should not be treated as the cause of Kneeland’s suicide.

CTE research continues to examine how repeated head impacts affect the brain over time. A diagnosis after death can document changes in brain tissue, but it cannot by itself explain every aspect of a person’s behavior or establish a direct cause of suicide.

What Was Stage 1 CTE in Marshawn Kneeland’s Brain?

Stage 1 represents the earliest stage in the four-stage system researchers use to describe the severity of CTE-related changes in the brain.

The Boston University CTE Center examined Kneeland’s brain tissue after his death and diagnosed Stage 1 CTE. The Concussion & CTE Foundation made the diagnosis public on July 7, 2026, after Kneeland’s family released the postmortem findings.

Researchers continue to study the disease and its relationship to symptoms during life. The presence of early-stage CTE does not automatically show how the condition affected an individual or what role it played in a particular event.

What Did the CTE Examination Find?

The postmortem examination found Stage 1 CTE in Kneeland’s brain. Boston University’s CTE Center reached that diagnosis after examining his brain tissue, and his family later made the findings public through the Concussion & CTE Foundation.

The finding adds to the medical record surrounding Kneeland’s death, but it does not provide a standalone explanation for his suicide.

Researchers have repeatedly pointed out the difference between identifying CTE pathology and proving that CTE caused a specific symptom, behavior, or death. That distinction remains important when discussing Kneeland’s case.

Marshawn Kneeland’s NFL Career

The Dallas Cowboys selected Marshawn Kneeland with the 56th overall pick in the second round of the 2024 NFL Draft. He joined the team after playing college football at Western Michigan University.

Kneeland appeared in 11 games during his rookie season and started one of them. An injury kept him out of six games that year.

His second season began with a larger role. Kneeland played in seven of Dallas’ first nine games in 2025 and recorded one sack, 15 tackles, and six quarterback pressures before his death.

He finished his NFL career with 18 regular-season appearances and four starts.

Marshawn Kneeland’s Last NFL Game

Kneeland played his final NFL game on November 3, 2025, when the Cowboys faced the Arizona Cardinals.

Dallas lost 27–17, but Kneeland produced a memorable moment by recovering a blocked punt in the end zone for his first NFL touchdown.

Three days later, he died in Frisco. The touchdown against Arizona became the final scoring play of his NFL career.

Marshawn Kneeland’s College Career

Before entering the NFL, Kneeland played at Western Michigan University.

His college career put him on the path to the NFL Draft, where Dallas selected him in the second round in 2024. The Cowboys used the 56th overall pick on the defensive end.

Kneeland then spent the remainder of his football career with Dallas.

Marshawn Kneeland’s Age at Death

Marshawn Kneeland was 24 years old when he died.

The Frisco Police Department and Dallas Cowboys both identified him as 24 following his death.

His death came less than two years after Dallas selected him in the 2024 NFL Draft, during only his second professional season.

Marshawn Kneeland and Mental Health

Mental health became part of the public record because Frisco police said they had received information that Kneeland had expressed suicidal ideation before officers found him.

That statement does not provide a complete account of what Kneeland experienced or explain the reasons behind his decision. It only reflects information investigators reported as part of their initial response.

The Frisco Police Department included the 988 Suicide & Crisis Lifeline in its statement after his death, highlighting the availability of crisis support for people experiencing suicidal thoughts or emotional distress.

What Happened After His Death?

The Dallas Cowboys mourned Kneeland after his death and remembered him as a young player whose professional career had only recently begun.

His death came during the 2025 NFL season, just days after he scored the first touchdown of his career. The Cowboys and people around the team publicly expressed their grief following the news.

The circumstances also brought renewed public attention to suicide prevention and research into the long-term effects of repeated head impacts in football.

Why Was Marshawn Kneeland’s CTE Diagnosis Released Later?

The CTE diagnosis appeared months after Kneeland’s death because researchers can currently confirm CTE only by examining brain tissue after death.

Boston University’s CTE Center performed the postmortem examination, and the Concussion & CTE Foundation announced the Stage 1 diagnosis on July 7, 2026. Kneeland’s family chose to make the findings public.

That process explains why the CTE information did not appear in the original police statement from November 2025. Police were dealing with the immediate death investigation, while the brain examination required a separate postmortem research process.

Does Marshawn Kneeland’s CTE Diagnosis Explain His Suicide?

No. The CTE diagnosis does not establish a direct explanation for Kneeland’s suicide.

The Boston University examination found Stage 1 CTE, but researchers have warned against treating that finding as proof that CTE caused his death. Suicide can involve multiple factors, and the presence of CTE alone cannot identify one specific cause.

The clearest description of the evidence is therefore straightforward: Kneeland died by suicide, and a later postmortem examination found Stage 1 CTE in his brain. Current research does not establish that the CTE caused his suicide.

Marshawn Kneeland’s Legacy

Marshawn Kneeland’s NFL career lasted two seasons, but his death became part of a wider discussion about suicide prevention and the long-term effects of repeated head impacts in football.

His final game came only three days before his death, and he scored the first touchdown of his NFL career in that game. The later brain examination added another significant fact to his story by identifying Stage 1 CTE.

The available evidence separates those two issues clearly. Kneeland died by suicide, while the postmortem examination found early-stage CTE; current research does not establish that the CTE diagnosis caused his death.
