There was a weight issue Friday afternoon in Omaha, Nebraska, for HBO’s scheduled main event Saturday night, but not for the network’s co-featured fight.

John Molina Jr., (29-6, 23 KOs), of Covina, California, weighed in at 144 pounds, four pounds overweight, for the main event – a 12-round, 140-pound fight against Omaha’s Terence Crawford (29-0, 20 KOs), the defending WBC/WBO super lightweight champion. Crawford weighed in below the 140-pound limit, at 139.6 pounds.

Molina was given the standard two hours to lose the four pounds and come back to the scales at CenturyLink Center, where Saturday’s seven-bout card will take place. If Molina cannot weigh in a second time at 140 pounds or less, the scheduled 12-round fight is expected to proceed as planned, just without Crawford’s titles at stake.

Below are the weights from the non-televised portion of the undercard:

Ten rounds, light heavyweights: Sean Monaghan (27-0, 17 KOs), Long Beach, New York, 179.2 pounds, vs. Fernando Castaneda (24-11, 15 KOs), Aguascalientes, Mexico, 177.8 pounds.

Eight rounds, super lightweights: Mike Reed (20-0, 12 KOs), Waldorf, Maryland, 142 pounds, vs. Sidney Siqueira (26-11-1, 17 KOs), Sao Paulo, Brazil, 141.6 pounds.

Six rounds, lightweights: Kevin Ventura (3-0, 2 KOs), Omaha, Nebraska, 135 pounds, vs. Gregorio Perez Herrera (4-1-1, 1 KO), Denver, 134.4 pounds.

Four rounds, light heavyweights: Steve Nelson (4-0, 4 KOs), Omaha, Nebraska, 174 pounds, vs. Chris Harris (2-1-2, 2 KOs), Kansas City, Kansas, 175 pounds

Four rounds, super middleweights: Chris Arguello (1-1-1, 1 KO), Denver, 168.4 pounds, vs. Manuel Medrano (4-4, 2 KOs), Tlaquepaque, Mexico, 167 pounds
