An undisclosed injury to John Hathaway has forced a welterweight shakeup at UFC 189 on July 11 in Las Vegas.
Hathaway's original opponent, Gunnar Nelson (13-1-1) will now face Brandon Thatch (11-2), who was already scheduled to fight John Howard at UFC 189, which takes place at MGM Grand Garden Arena in Las Vegas.
Nelson hasn't fought since suffering the first loss of his career in October, a five-round split decision to Rick Story. The 26-year-old welterweight hails from SBG Ireland, the same camp to Pendred and featherweight title contender Conor McGregor.
Thatch is also coming off a loss in his last fight. The Denver-based welterweight suffered fourth-round submission loss to former lightweight champion Benson Henderson on Feb. 14. The loss snapped a 10-fight win streak for Thatch.
Hathaway (17-2) has struggled to stay healthy throughout his UFC career. The 27-year-old hasn't fought since March 2014 and missed all of 2013 due to injury. He is 7-2 all-time in the Octagon.
A featherweight title fight between Jose Aldo (25-1) and McGregor (17-2) is currently scheduled to headline UFC 189.
