Fulton is priced at $0.63 per share to win and Wilson is $0.37 per share.
In the main event, Spence is coming off a three-year layoff after suffering his first loss ever in a superfight against Terence Crawford on July 29, 2023. Crawford won that matchup via TKO to take the WBA, WBC and IBF welterweight titles off Spence. He's now 28-1 in his career with 22 wins via knockout.
Meanwhile, Tszyu scored a unanimous decision victory over Denis Nurja in April to improve to 27-3 in his career. He won his first 24 bouts as a professional and was a WBO light middleweight champion, but has lost three of his last six fights.
