Roberson and Vettori were originally scheduled to face each other at UFC Jacksonville last week. However, the fight was canceled when Roberson was unable to compete on the night of the event after being diagnosed with rhabdomyolysis.
Vettori — who had a heated staredown with Roberson on the day of weigh-ins — was not pleased at the time and lashed out at his opponent leading to a near physical altercation.
The UFC was originally planning to hold its debut show in Kazakhstan on June 13. However, it looks like the promotion will now be hosting most of its future events at the Apex facility in Las Vegas.
