Earlier this afternoon the mixed martial arts world was left in shock after news broke that tonight’s UFC 234 main event had been cancelled.

This evening’s main event was expected to feature reigning UFC middleweight champion Robert Whittaker taking on surging division contender Kelvin Gastelum.

However, earlier this afternoon UFC President Dana White revealed to ESPN’s Brett Okamoto that Whittaker had been forced off the card due to injury.

According to the brash UFC boss, Robert Whittaker had been complaining about pain in his abdomen area. “The Reaper” was then taken to the hospital where doctors found a hernia. White added that Robert Whittaker will be undergoing the surgery for his hernia later today.

Despite some courageous offers from former UFC title challengers Donald Cerrone and Chael Sonnen, Kelvin Gastelum was ultimately pulled from tonight’s UFC 234 lineup.

Gastelum would later release a statement on his title fight cancellation, you can read that here.

UFC 234 will now be headlined by a three-round middleweight main event featuring former division kingpin Anderson Silva taking on rising contender Isreal Adesanya.

Check out how the pros reacted to tonight’s shocking UFC 234 main event cancellation below.
