QUINCY, Mass. (March 31, 2019) - Former New England welterweight champion

Derek "The Surgeon" Silveira has a new opponent for his April 12th main event fight for the vacant N.E. welterweight title on a stacked "Riot at The Rim" card, presented by Granite Chin Promotions (GSP), at The Rim in Hampton, New Hampshire.

Silveira (15-2, 8 KOs), fighting out of Salem, MA, will now take on 19-year-old Mexican knockout specialist Roberto "Viejo" Valenzuela, Jr, (14-0, 13 KOs), who has replaced injured Travis "The Outlaw" Demko (8-1, 1 KO), of Stoughton, MA, in the scheduled eight-round headliner.

"Losing Travis was tough blow but the determination to put on a jam-packed card didn't waiver," GCP promoter Chris Traietti said. "Derek's camp was ready for a step-up fight and, quite frankly, Granite Chin was ready to make a statement in 2019. After a few days with the phone glued to my ear, Roberto Valenzuela Jr stepped up and took the fight. He's bringing a great record at 14-0 to the table and Derek didn't even flinch at the offer."
