Mike Tyson is gearing up for his fight with Jake Paul.

Following Paul’s knockout victory over Mike Perry Saturday, Tyson posted a countdown for his fight against Paul and also included a video of him watching Paul’s introduction to the fight against Perry.

This comes after Paul called out Tyson following the victory, declaring “Mike Tyson, you’re next,” during his post-fight interview.

The Paul-Tyson fight nearly occurred on Saturday night, as the original date was for June 20. Tyson postponed the fight due to suffering an ulcer flare up, and that led to Perry stepping in to face Paul instead.

Paul knocked down Perry in the sixth round and improved his overall record to 10-1 with seven knockouts. While it has been an impressive run for the 27-year-old, his accomplishments pale in comparison to what the 57-year-old Tyson has done.

Tyson was the undisputed world champion from 1987-1990 and boasts an overall record 50-6-2 with 44 knockouts. His last professional fight was in 2005 when he fell to Kevin McBride while his last exhibition fight came in 2020 when he fought to a draw with Roy Jones Jr.

The fight with Jones Jr. saw Tyson fight a boxer just a two-year age gap, but the significant age disparity between Tyson and Paul will make the upcoming bout interesting.

The fight is currently set for Nov. 15 at AT&T Stadium in Arlington, Texas.a
