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 the packed New York City streets. One World Trade Center is the tallest building in the Western Hemisphere and the highest point in New York City.

While the two initially exchanged pleasantries, the tension grew after Davis repeatedly touched Berinchyk’s world title. 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, as Puerto Rican star Xander Zayas (20-0, 12 KOs) defends his NABO and NABF junior middleweight straps against fellow unbeaten Slawa Spomer (20-0, 11 KOs).
