Super welterweight world champion Tony Harrison injured his ankle in training last week and has withdrawn from his title defense against former world champion Jermell Charlo that was scheduled to headline FOX PBC Fight Night on FOX and FOX Deportes Sunday, June 23 at Mandalay Bay Events Center in Las Vegas.

Harrison has an inner and outer ankle sprain with torn ligaments in his right ankle and he will be out for 10 weeks before he can resume training. Harrison and Charlo plan to have their rematch later this year.

Stepping in to replace Harrison for a 12-round fight is the always dangerous Jorge Cota (28-3, 25 KOs), who most recently lost a disputed split-decision in April on FS1 against Jeison Rosario.

The 31-year old from Los Mochis, Sinaloa, Mexico had scored three straight knockout victories before the defeat in April.

"Watching my Mexican brother Andy Ruiz fight last weekend, I am very motivated,'' said Cota.

"I saw how he got an unexpected chance to become a champion and surprise the world. He has inspired me to win this fight in the same way. I will shock the world on June 23 just like Andy did on Saturday, for Mexico, the country that I love. This is the most important fight of my career.''

"As we have seen from Andy Ruiz's incredible upset of Anthony Joshua in the heavyweight championship fight on Saturday night, replacement fighters are not to be taken as a joke,'' said Tom Brown, President of TGB Promotions.

"Jorge Cota is a dangerous fighter. He has heavy hands and he's looking for an opportunity to make a statement. Jermell Charlo realizes just how serious this is and he wants to get his title back. I know he's going to be prepared to make his own statement."
