The UFC are yet to announce a replacement, but could look locally to do so. Australian MMA promotion company Eternal is hosting a fight night in Auckland the night before the UFC card, with some of the top local fighters on the card. At this stage, the Eternal card is being headlined by a lightweight bout between Kiwi duo BJ Bland and Iain Blade.
Bland (14-10), part of the City Kickboxing stable, shapes up as the likely choice if the UFC wanted to book a local fighter, with recent bouts against Potter and Australian Abel Brites - who fought Mullarkey, Potter and Kiwi UFC star Brad Riddell - among his four previous opponents.
"He's a bloke that just doesn't get enough credit," Potter told the Herald of Bland. "BJ Bland is a sensational fighter and I feel he might be one of those local guys who doesn't get enough credit. He's in a big gym with a lot of superstars over there but he would give anyone on the scene, both locally and internationally, a hard time. He's a very, very talented fighter and I hope he does get a shot on the big stage."
There's no guarantee the UFC would offer the bout to a local, however, and could try to find a replacement already signed with the promotion.
Mullarkey's withdrawal from the card makes him the fourth athlete scheduled to fight in Auckland to be removed from the card. Australian Tyson Pedro was also ruled out due to injury, with the UFC then cancelling his bout with Vinicius Moreira rather than replacing him, while flyweight Rachael Ostovich was removed from her bout against Shana Dobson due to undisclosed personal reasons. Ostovich was replaced by Priscila Cachoeira.
