Press Release: Undefeated teenager Jorge Paez Jr. has a new opponent, veteran Rafael Urias, for his six-round, lightweight bout Friday, Dec. 15, in Mexicali, Mexico. “This change in opponents won’t bother me,” said Paez Jr., the son of former featherweight champion Jorge Paez.  “I’m ready.  I feel I’m in better shape and more focused than I have been in eight months.”  A confident Paez Jr. took time out from his training Wednesday to pass out hundreds of toys, provided by Sycuan Ringside Promotions, to boys and girls in his hometown of Mexicali. The 19-year-old Paez Jr., who has a record of 11-0 with seven KOs, is coming off four decision  wins. Urias, from Los Mochis, Mexico, is reportedly a veteran of almost 30 bouts but boxrec lists him as 2-13-1. He replaces Joel Padilla, who injured his left hand while training for Paez.
