In what could be his last fight at super featherweight, Vasyl Lomachenko met the 130-pound limit Friday afternoon.

The Ukrainian southpaw weighed in at 129.6 pounds for his 12-round title defense Saturday night against Jason Sosa in Oxon Hill, Maryland. Sosa weighed in at 130.4 pounds on his first try.

The former WBA world super featherweight champion stripped naked, but still weighed 130.2 pounds on his second try Friday. He was given the standard two hours to lose those two ounces.

If Sosa cannot make 130 pounds when he returns to the Maryland commission’s scale, Lomachenko’s WBO world super featherweight title won’t be at stake Saturday night.

The 29-year-old Lomachenko is a 25-1 favorite entering their fight at MGM National Harbor, just outside of Washington, D.C. When asked how he planned to upset such a uniquely talented, favored fighter, Sosa said, “by knocking Lomachenko out.”

Lomachenko, a two-time Olympic gold medalist, has suggested that he’ll move up to the lightweight division if he defeats Sosa (20-1-4, 15 KOs), of Camden, New Jersey, and cannot secure the fights he wants at 130 pounds.

The fight he wants most is a rematch against Orlando Salido. Mexico’s Salido (43-13-4, 30 KOs, 1 NC) beat Lomachenko by split decision in just the second pro fight for Lomachenko three years ago in San Antonio.

HBO will televise the Lomachenko-Sosa fight as the main event of a “World Championship Boxing” tripleheader scheduled to start at 10 p.m. ET.

The four fighters set to participate in the other two TV bouts made weight without issue Friday.

Ukraine’s Oleksandr Usyk (11-0, 10 KOs), a 2012 Olympic gold medalist, weighed in at 199.4 pounds for a 12-round defense of his WBO world cruiserweight title against Las Vegas’ Michael Hunter (12-0, 8 KOs). Hunter, a 2012 American Olympian, weighed 198 pounds.

Another unbeaten Ukrainian, Oleksandr Gvozdyk (12-0, 10 KOs), weighed in at 174.2 pounds for his 10-round light heavyweight fight against Cuban contender Yunieski Gonzalez. Miami’s Gonzalez (18-2, 14 KOs) weighed 174.8 pounds.
