An injury has forced a change to next month’s UFC show in Australia.

Ireland’s Neil Seery (14-10 MMA, 1-1 UFC) is out of his flyweight bout against Richie Vaculik (10-2 MMA, 1-1 UFC). In Seery’s place steps Louis Smolka (7-1 MMA, 1-1 UFC) on short notice.

UFC officials announced the new matchup on Tuesday. Seery said on his Twitter account that a rib injury is what will keep him out. He had originally been a replacement for Ray Borg.

Featuring a middleweight matchup between Luke Rockhold and Michael Bisping, UFC Fight Night 55 takes place Nov. 8 at Allphones Arena in Sydney. The entire card will stream on UFC Fight Pass in the United States.

Smolka, from Hawaii, is looking to rebound from the first loss of his pro career. In May, he dropped a split decision to Chris Cariaso at UFC Fight Night 40 in Cincinnati after starting a perfect 7-0 with six finishes. Cariaso went on to challenge for the flyweight title.

Vaculik, from Australia, will be fighting in front of his home fans. Like Seery, he dropped his UFC debut, but rebounded and now goes after two in a row. This past December, he was stopped in the first round by Justin Scoggins. But he beat Roldan Sangcha-an in June in New Zealand.

Seery, a longtime Cage Warriors fighter, made his UFC debut in March in London, but dropped a unanimous decision to Brad Pickett. But he rebounded in July in his home city of Dublin when he topped Phil Harris at UFC Fight Night 46. He was going after two in a row in Australia before the injury.

With the change, the UFC Fight Night 55 lineup now includes:

MAIN CARD (UFC Fight Pass, 10 p.m. ET)

Luke Rockhold vs. Michael Bisping

Al Iaquinta vs. Ross Pearson

Clint Hester vs. Robert Whittaker

Walt Harris vs. Soa Palelei
