Stephen Fulton’s move up in weight didn’t proceed as planned.

Fulton came in two pounds over the limit Friday for his 12-round fight for O’Shaquie Foster's WBC 130-pound title Saturday night at Frost Bank Center in San Antonio. The sanctioning body initially announced they would move forward with their bout, but Fulton wasn't eligible to win the belt.

The WBC later divulged, however, that Fulton and Foster will fight for its vacant interim lightweight title.

The winner will become the mandatory challenger for Shakur Stevenson, the WBC's 135-pound champion. Stevenson is set to go up to junior welterweight to challenge Ring and WBO 140-pound champ Teofimo Lopez on January 31 in New York.

The WBC originally announced that the January 10 fight between Ricardo Nunez and Jadier Herrera would be contested for its interim lightweight title.

It appears for the time being that Foster (23-3, 12 KOs), of Orange, Texas, and Philadelphia's Fulton (23-1, 8 KOs) will keep their 130- and 126-pound titles, respectively.

The 31-year-old Fulton acknowledged during the buildup toward his fight with Foster that he had difficulty squeezing down to the featherweight limit of 126 pounds. Fulton is a former WBC and WBO 122-pound champion.

He beat Brandon Figueroa by unanimous decision in their 12-round rematch in his last fight February 1 at T-Mobile Arena in Las Vegas. Fulton won the WBC featherweight title from Figueroa.

The Foster-Fulton fight will be part of Premier Boxing Champions’ pay-per-view undercard (8 p.m. ET; $74.99). Mexico’s Isaac Cruz (28-3-1, 18 KOs) is scheduled to defend his WBC interim super lightweight championship against American Lamont Roach (25-1-2, 10 KOs) in the 12-round main event.
