Sebastian “The Towering Inferno” Fundora has emerged as the replacement for injured Keith Thurman to meet WBO 154-pound champion Tim Tszyu March 30 in the debut Amazon Prime Video pay-per-view card in Las Vegas, BoxingScene has learned.

Two officials with knowledge of the negotiations said Premier Boxing Champions product Fundora (20-1-1, 13 KOs) will move up from his spot opening the pay-per-view portion of the card to instead fight Tszyu (24-0, 17 KOs) in the main event at T-Mobile Arena.

Fundora, standing at a staggering 6-feet-5 ½ and wielding an 80-inch reach, adds significant intrigue to the bout given his unique body frame and tendency to engage in all-action firefights.

Additionally, because his previously scheduled bout against Serhii Bohachuk was to be for the vacant 154-pound belt, WBC President Mauricio Sulaiman tells BoxingScene his executive board is huddling to decide whether to make Tszyu-Fundora a WBO-WBC unified title affair.

Fundora, from Coachella, Calif., is coming off a seventh-round knockout loss to Brian Mendoza in April.

Before that, in 2022, he stopped former 154-pound title challenger Erickson Lubin and defeated former welterweight title challenger Carlos Ocampo by a wide unanimous decision.

Officials are still assessing where to place Bohachuk on the card. Bohachuk is promoted by Tom Loeffler.
