How to Watch "Mike Tyson: The Knockout" on ABC On 5/25/21 at 12:00 PM EDT From Michael Jordan to Tiger Woods, documentaries delving into the lives of sports icons are now par for the course. It is therefore no surprise to see Mike Tyson is next the next taxi off that particular rank, with the 54-year-old the focus of Mike Tyson: The Knockout, a two-part ABC documentary which premieres today (May 25). Even within boxing's rich and outlandish tapestry, few fighters have enjoyed veneration and simultaneously attracted public condemnation as often as Iron Mike did. From marginalized Brooklyn kid to the dominant force in boxing's premier weight division, at his peak Tyson was a near-peerless fighter—he reigned as the undisputed world heavyweight champion for three years.
