Canadian middleweight Patrick Cote and Australian fighter Kyle Noke will serve as head coaches on a new international edition of “The Ultimate Fighter” called “TUF Nations: Canada vs. Australia.” UFC officials today announced the plan. The show, tentatively scheduled to debut in early 2014, will feature welterweight UFC hopefuls. Tryouts will begin in September for “TUF Nations: Canada vs. Australia,” which is the 22nd edition of the UFC’s long-running reality show. The tryouts will take place in Sydney and Toronto, though details won’t be released until next month.
