Today we announced, on behalf of the Kneeland family, that former Dallas Cowboys DE Marshawn Kneeland has been diagnosed with stage 1 CTE by our research collaborators at @bu_cte. Kneeland died by suicide in November 2025 at 24 years old.

Despite playing in the modern era of concussion protocols and better helmets, he still developed CTE. What that tells me is we have no reason to believe the current generation is at a lower risk of CTE than previous generations. Concussion protocols do not prevent CTE, because CTE is caused by repeated head impacts, not just concussions. If we want to reduce CTE risk, we must implement CTE prevention protocols and aggressively reduce the number and strength of head impacts at every level of the game.

Suicide is complex and multifactorial. A post-mortem CTE diagnosis should not be considered the cause of a suicide and is not known to be a risk factor for suicide.

We encourage anyone worried about suspected CTE symptoms to reach out to he Concussion & CTE Foundation HelpLine team for support at https://t.co/Vj1Snych3P.

If you or someone you know is struggling, the 988 Suicide & Crisis Lifeline is available 24/7 by calling or texting 988.

"Scientists studied how brain injuries affect sleep patterns in mice, like if a soccer player kept getting hit in the head and couldn't sleep well afterwards."

Come check out @Ryanamartin92 and his work involving the utilization of BioID to track the circadian secretome of skeletal muscle! #SRBR2022

[Dr. Jan-Frieder Harmsen @247muscle]

Skeletal muscle does not only have a #circadian clock in 🪰🐭 BUT also in 👨 !

Tonight at my poster #T40 #SRBR2022, you will see how the human muscle ticks, how its clock is altered between young healthy and older insulin-resistant men & what metabolic consequences evolve!
