RIO DE JANEIRO – More than 600 UFC hopefuls attended Monday’s open tryouts for “The Ultimate Fighter: Brazil 4.” While there, UFC matchmaker Joe Silva took MMAjunkie behind the scenes of the process.

The tryouts took place in Rio de Janeiro (check out today’s USA TODAY story on them), where 16 lightweights and 16 bantamweights ultimately will earn a shot on the most successful international edition of the UFC’s long-running reality series.

Check out the above video as Silva explains what makes the Brazil fighters special, shows us the actual tryout process, and watches the reaction from the competitors when they learn the show will head to Las Vegas this season.
