MANILA – Boxing trainer Jorge Rubio is seeking an explanation from Guillermo Rigondeaux’s sudden decision to replace him.

Shortly before getting the Nonito Donaire fight, Rigondeaux turned his back on Rubio and hired his long-time amateur boxing coach Pedro Diaz of Cuba.

"I have nothing against Rigo and I wish him well, but I'm still waiting for an explanation for what happened,” said Rubio in Boxing Scene.

Rigondeaux, who remains unbeaten in 11 pro fights, has  changed trainers twice.

Before hiring Rubio, Rigondeaux worked with Manny Pacquiao’s trainer, Freddie Roach.

Rubio said he has tried reaching Rigondeaux to get an explanation, but the Cuban boxer refused to respond.

"What bothers me is that Rigo and I had an open channel of communication, or so I thought, and I do not think he was completely honest with me. If he was pressured not to work with me, I should have been told. If it was by his own free will, I equally deserved an explanation. At this point, he is not being professional.''

The Cuban’s co-promoter, Boris Arencibia of Caribe Promotions, has an answer to Rubio’s queries.

"It is very common for a boxer to make a technical change from time to time to get different results. Rubio's efforts are appreciated, but we felt that it was time to move in another direction in that area of the corner,” he said.
