Keyshawn “The Businessman” Davis was all business three days before a career-defining fight that could propel him to champion status. Davis will challenge WBO lightweight champion Denys Berinchyk Friday evening at The Theater at New York City's Madison Square Garden. Davis (12-0, 8 KOs) and Berinchyk (19-0, 9 KOs) kicked off fight week with a face-off at One World Observatory at One World Trade Center, 102 stories above New York City streets. One World Trade Center is the tallest building in the Western Hemisphere. While the two initially exchanged pleasantries, the tension grew after Davis repeatedly touched Berinchyk’s championship belt. The two eventually had to be separated and will meet again tomorrow at the final press conference. No extra security was needed for the co-feature combatants, Puerto Rico's Xander Zayas (20-0, 12 KOs) and fellow unbeaten Slawa Spomer (20-0, 11 KOs). Berinchyk-Keyshawn, Zayas-Spomer, and a middleweight bout between Vito Mielnicki, Jr. and Conor Coyle will be broadcast live on ESPN, ESPN Deportes, and ESPN+ at 9 p.m. ET/6 p.m. PT.
