Kelvin Gastelum has agreed to replace Paulo Costa and square off against Robert Whittaker in the UFC on ESPN 22 headliner on April 17.
ESPN was first to report the new booking. Costa was forced to pull out of the middleweight contest because an illness had limited his training leading up to the fight. UFC on ESPN 22 takes place at the UFC Apex in Las Vegas.
Gastelum was intially supposed to face Whittaker in a middleweight title bout at UFC 234 in February 2019 before Whittaker withdrew on the day of the fight to undergo surgery for a hernia.
