Angelo Leo and Tramaine Williams have one last hurdle to overcome now that they have made weight for their 12-round, 122-pound title fight.

Leo, Williams and the four other boxers scheduled to compete in fights Showtime will televise are awaiting the results of the final COVID-19 tests they took before their weigh-in Friday afternoon at Mohegan Sun in Uncasville, Connecticut. The results of those tests should become available by Friday night.

If each of those six fighters have tested negative for COVID-19, Showtime’s altered three-fight card will proceed as planned Saturday night at Mohegan Sun Arena.

Leo (19-0, 9 KOs), of Albuquerque, New Mexico, officially weighed 121 pounds when he stepped on the Mohegan Tribe Department of Athletic Regulation’s scale Friday. Williams (19-0, 6 KOs, 1 NC), of New Haven, Connecticut, weighed in at 121½ pounds for Showtime’s main event.

Leo, 26, and Williams, 27, will fight for the unclaimed WBO junior featherweight championship Mexico’s Emanuel Navarrete vacated recently to move up to the 126-pound division.

Leo, who is ranked second by the WBO, was supposed to face Stephen Fulton for that title Saturday night. Philadelphia’s Fulton (18-0, 8 KOs), the WBO’s number one contender, tested positive for COVID-19 and was removed from the main event Wednesday.

Williams was scheduled to face Ra’eese Aleem in a 12-round, 122-pound WBA elimination match. The 30-year-old Aleem, of Muskegon, Michigan, instead will battle late replacement Marcus Bates, of Washington, D.C.

Aleem and Bates made weight before Leo and Williams weighed in Friday.

Aleem (16-0, 10 KOs) came in at 121¼ pounds. Bates (11-1-1, 8 KOs) also weighed 121¼ pounds.

The 26-year-old Bates will attempt to avenge his lone loss against Aleem, who beat him by unanimous decision in their eight-rounder in April 2018 at 2300 Arena in Philadelphia.

Earlier Friday, light heavyweights Joseph George and Marcos Escudero made weight for their own rematch Saturday night.

Houston’s George got on the scale at 174¼ pounds. Argentina’s Escudero weighed in at 173½ pounds.

George (10-0, 6 KOs) defeated Escudero (10-1, 9 KOs) by split decision in their 10-round encounter November 15 at WinnaVegas Casino Resort in Sloan, Iowa. George won their fight on two scorecards (97-94, 97-93), but he lost on the other card (96-94).

Showtime’s telecast, its first boxing broadcast since March 13, is set to begin at 9 p.m. ET/6 p.m. PT.
