Oscar Valdez hit the headlines earlier this year when he produced a stunning knockout to take the WBC super-featherweight belt from Miguel Berchelt in a big upset.
Tonight, the Mexican puncher makes the first defence of his world title when he steps in the ring with former amateur nemesis, Robson Conceicao.
Can Valdez add to his impressive 2021 or will his reign be a short one?
Valdez vs. Conceicao will be shown on ESPN in America. Sky Sports will broadcast the fight in Britain.
Valdez vs. Conceicao will take place at Casino Del Sol in Tucson, Arizona.
