However, the bout was cancelled on the day of the weigh-ins, after Waldburger passed out while cutting weight. The pairing had been rescheduled for this event,[5] but it was scrapped yet again after Waldburger pulled out of the bout on May 19 due to undisclosed reasons.[6] He was replaced by promotional newcomer Darren Till.[7]
Renato Moicano was expected to face Mirsad Bektić at the event. However, Moicano pulled out of the fight in late April due to a knee injury and was replaced by Lucas Martins.[9]
On June 18, it was announced that Rony Jason tested positive for hydrochlorothiazide, which is a banned diuretic, therefore his submission victory against Damon Jackson was overturned and he received a nine-month suspension.[13] The UFC rescinded Jason's $50,000 "Performance of the Night" award.[14] Jason requested an analysis of his second sample, which also came positive for the diuretic.[15]
