Serhii Bohachuk couldn’t secure the chance to avenge his most recent defeat, but he will get another opportunity to beat the only other opponent who has defeated him as a professional.

TKO announced Tuesday that a rematch between Bohachuk and Brandon Adams will be part of the Canelo Alvarez-Terence Crawford undercard September 13 at Allegiant Stadium in Las Vegas. The Bohachuk-Adams rematch, a 10-rounder that will be contested at a contracted catch weight of 156 pounds, will be streamed on YouTube, along with five other bouts.

American heavyweight Jermaine Franklin (23-2, 15 KOs), of Saginaw, Michigan, will face 6-foot-9 Kazakh knockout artist Ivan Dychko (15-0, 14 KOs) in another 10-rounder on the YouTube portion of the undercard.

The Alvarez-Crawford showdown and its main undercard bouts will be streamed by Netflix, to a subscriber base that exceeds 300 million.

Ukraine’s Bohachuk (26-2, 24 KOs) led Adams comfortably on all three scorecards when he was drilled with a left hook that abruptly ended their scheduled 10-rounder early four years ago in Guaynabo, Puerto Rico.

Bohachuk’s head snapped back and he went down with 26 seconds to go in the eighth round. A disoriented Bohachuk beat referee Ramon Pena’s count, but he stumbled and their fight was stopped in March 2021.

Adams (25-4, 16 KOs), of Whittier, California, had trailed by scores of 69-63, 68-64 and 68-64.

Bohachuk, 30, has won eight of his nine fights since that defeat.

His only loss during that stretch was a “Fight of the Year” candidate in which he dropped knockout artist Vergil Ortiz Jr. twice. Ortiz, of Grand Prairie, Texas, recovered from each knockdown quickly and beat Bohachuk by majority decision in August 2024 in Las Vegas.

Bohachuk’s handlers have tried to put together a rematch with Ortiz, but it hasn’t happened. Ortiz (23-0, 21 KOs) is instead expected to defend his WBC interim 154-pound crown against Erickson Lubin (27-2, 19 KOs) on October 18.

Adams, 36, has been a lot less active than Bohachuk since they fought.

He’ll end a 9½-month layoff when he boxes Bohachuk again. Adams lost his last bout to Greek prospect Andreas Katzourakis (16-0, 11 KOs), who won their 10-rounder by split decision last November 22 in Atlanta.
