Former unified featherweight champion Yuriorkis “El Ciclon de Guantanamo” Gamboa (27-2, 17 KOs) will step in to fight Jason “El Canito” Sosa (20-2-4, 15 KOs) in a 10-round super featherweight fight at the Theater at Madison Square Garden in the televised opener to Kovalev vs. Shabrankskyy. The event takes place Saturday, Nov. 25 and will be televised live on HBO. Gamboa is replacing Robinson “Robin Hood” Castellanos, who pulled out of this fight due to an injury.

“This should be a solid fight between two guys, the same size, who like to hurt people,” said Russell Peltz, Hall of Fame Promoter of Peltz Boxing Promotions.”It’s a better matchup, style-wise, than the one between Jason [Sosa] and Robinson Castellanos.”
