John Brenkus, host and co-creator of ESPN's "Sport Science," died on Saturday, according to an announcement made on his X account Monday night. He was 54.
The Emmy-award winning host had been dealing with depression, the statement said.
"John lost his fight with this terrible illness on May 31st, 2025," the post read. "His heartbroken family and friends request privacy at this time, and encourage anyone who is struggling with depression to seek help."
Brenkus was also the founder of Brinx.TV and co-founder of Base Productions.
Brenkus opened up about his depression and suicide attempt to Marcellus Wiley, ESPN colleague and former NFL player, in January 2023. He said that when he was living in Park City, Utah, after selling his company and "Sport Science," he felt isolated and spiraled into a "deep, deep depression."
"I was flat-out suicidal," Brenkus said. "So much so, I had a noose tied around my neck. I was ready to do it."
Brenkus credited his dog, Zepplin, with rescuing him by tugging on his jeans and pulling him out of his "suicidal funk." The sports host then explained seeing multiple psychologists and psychiatrists trying to receive help, until one doctor in Virginia helped him find the "right path."
"I have never been depressed since, a day in my life, from that moment forward," Brenkus said at the time.
Wiley reposted the announcement of Brenkus' death, writing "RIP" with praying and heart emojis.
Brenkus' "Sport Science" series aims to uncover "sports’ biggest myths and mysteries by using cutting-edge technology to measure momentum, friction and the laws of gravity," ESPN describes on its website. The series won six Emmy awards, first airing on FOX Sports in 2007 before moving to ESPN.
In a tribute on ESPN, Brenkus was described as "an innovator, an entertainer and an educator" who will be missed by many.
