All seemed quiet at an uneventful weigh-in at the MGM Grand in Las Vegas, as featherweights Juan Manuel "Juanma" Lopez and Rafael Marquez made weight for their showdown on Saturday night. Everything was quiet...that is...until we saw Celestino "Pelenchin" Caballero in a shoving match with Team Juanma moments after Lopez and Marquez weighed in.

As Team Juanma left the stage, Caballero, who was with his trainer Jeff Mayweather, tried to get Juanma's attention. Words were exchanged between the Puerto Rican and Panamanian. One of Juanma's bodyguards punched Caballero and another member of Team Juanma ran at Caballero before MGM security could restore order.

Caballero would later tell BoxingScene, "I just wanted to talk to Juanma and get him to agree to fight me. Words were exchanged and his bodyguard punched me and another member of his team came at me."

Caballero insisted he came with peaceful intentions, and only wanted to get a fight signed by the Puerto Rican star.

"If I wanted a brawl I would have brought my Panamanian crew. I just want to fight him. He wants to fight in the spring. Fight me!"

Team Juanma has yet to comment on the incident.
