UFC 189

UFC 189: Mendes vs. McGregor was a mixed martial arts event held on July 11, 2015, at the MGM Grand Garden Arena in Las Vegas, Nevada.^[4]

The event took place during the UFC's annual International Fight Week.^[5]

The event was expected to be headlined by a UFC Featherweight Championship bout between the then champion José Aldo and Conor McGregor.^[4] On June 23, it was reported that Aldo suffered a rib fracture and pulled out of the bout in light of the injury.^[6] On June 30, it was confirmed that Aldo indeed pulled out of the bout and that the interim championship bout would take place at this event. The bout remained the event headliner.^[7] On July 1, photographs of Aldo's scans were released and indicated that he had indeed suffered a fractured rib.^[8] On July 10, White claimed that Aldo did not have a broken rib as "every x-ray he sent out was of an old injury". He reaffirmed that Aldo had a "bruised rib and cartilage" and that the biggest problem was the weight cutting process being complicated by the injury. They later fought at UFC 194.^[9]

The co-main event featured a UFC Welterweight Championship bout between then champion Robbie Lawler and top contender Rory MacDonald.^[10] Their first fight at UFC 167 ended in a split decision victory for Lawler.^[11]

Matt Brown was briefly linked to a bout with Nate Diaz at the event.^[12] However, in mid-April, Brown announced that the pairing had been scrapped.^[13] Brown remained on the card against Tim Means.^[14]

A welterweight bout between Jake Ellenberger and Stephen Thompson was initially expected to take place at this event. However, in mid-May, the bout was made the main event of The Ultimate Fighter: American Top Team vs. Blackzilians Finale which took place a day later at the same venue.^[15]

John Hathaway was expected to face Gunnar Nelson at the event. However, on June 23, Hathaway pulled out of the bout due to an injury. This prompted a shift in another welterweight bout on the card as Brandon Thatch was pulled from his fight against John Howard to face Nelson, while Cathal Pendred was announced as Howard's new opponent. Pendred had previously fought only 28 days before the event, when he defeated Augusto Montaño at UFC 188.^[16]

Jeremy Stephens missed weight on his first attempt, coming in 3.5 lb overweight at 149.5 lb. After having made no attempts to cut further, he was fined 20 percent of his fight purse, which went to Dennis Bermudez.^[17]
