UFC 234: Robert Whittaker RULED OUT of title defense against Kelvin Gastelum with hernia
Whittaker was due to take on Gastelum in an eagerly-awaited match-up at the top of the bill on home soil at Rod Laver Arena on Sunday local time.
But the bout is now off after Whittaker was diagnosed with a hernia in his abdomen overnight, just hours before he was due to step into the Octagon.
ESPN’s Brett Okamoto reported the news, citing UFC chief Dana White.
He later said Whittaker would be undergoing surgery on Sunday for the problem.
