John Brenkus, the founder and host of ESPNâs Emmy-winning Sports Science show, has died aged 54 after âbattling depression,â a statement on his social media account said Sunday.
âIt is with profound sadness that we share the news that John Brenkus has passed away,â the statement on Brenkusâs X account read.
âJohn, co-founder of Base Productions, Founder of Brinx.TV, and co-creator and host of the six-time Emmy award-winning âSport Science,â had been battling depression.
âJohn lost his fight with this terrible illness on May 31, 2025. His heartbroken family and friends request privacy at this time, and encourage anyone who is struggling with depression to seek help.â
Sports Science first aired in 2007 on Fox Sports before moving to ESPN in 2010. Filmed inside a Los Angeles airport hangar or on location using a mobile laboratory, the show âuncovers sportsâ biggest myths and mysteries by using cutting-edge technology to measure momentum, friction and the laws of gravity,â per ESPN. It frequently saw Brenkus perform scientific tests as an âAverage Joeâ alongside professional athletes.
The series won six Sports Emmy Awards since its inception.

In a tribute on ESPN, Brenkus was described as an âinnovator, an entertainer and an educator.â
Fans on social media mourned his death. Among them was former NFL defensive end Marcellus Wiley, who worked with Brenkus on Brinx.TV and shared: âRIPâ on X alongside a heart emoji.
Two years ago, Brenkus told Wiley about his suicide attempt, which was foiled by his dog, Zeppelin.
âI come off of selling my company, selling Sports Science, ESPN... You know the isolation that you feel living in a mountain town, the cold weather, injuries, things not feeling right, I spiraled into a deep, deep depression," Brenkus said on Wileyâs podcast.
âI was ready to do it and my dog Zeppelin came to my rescue literally, pulled on my pants on my jeans, and was literally driving me crazy, wouldnât leave me alone,â Brenkus added.
âI literally picked up my phone, called my mom and said: âThereâs something wrong with me. I am mentally lost.ââ
