Chris Colbert Remains Unbeaten, Tops Tugstsogt Nyambayar

“We had a tremendous training camp,” said Colbert. “We sparred a lot with a bigger guy in Michel Rivera, so I had a lot of practice using my speed and jab in camp. The jab is always a key in this sport.”

Mongolia’s Nyambayar (12-2, 9 KOs), who now fights out of Los Angeles, stepped in to fight Colbert on less than two weeks’ notice, replacing former champion Yuriorkis Gamboa after he suffered a training camp injury. Nyambayar had successful moments in his 130-pound debut, with Colbert even noting the Olympic silver medalist’s power, but he was unable to keep up a sustained attack or keep the busier Colbert from controlling the tempo.

“I’m so excited and beyond happy to get this win,” said Rivera. “Fernández was a strong, experienced opponent that forced me to change the game plan I had going in.”
