All of the headline bouts at UFC 280 are still scheduled to take place at this moment in time. However, many prelim bouts didn't survive the test of time in Abu Dhabi.
Yamato Nishikawa was meant to be taking on Magomed Mustafaev in the 155lbs division, but the Japanese fighter has been pulled from the card due to contract issues.
Mustafaev was originally meant to face Jamie Mullarkey in the lightweight division. However, the Australian fighter also had to withdraw from the contest, this time due to an injury sustained during the lead-up to the bout.
Another contract issue saw Slim Trabelsi pulled from his upcoming fight against Parker Porter, who had his original contest against Hamdy Abdelwahab canceled.

Who is fighting on the UFC 280 main card?
As mentioned, the Abu Dhabi pay-per-view card is looking stacked and ready to go for this weekend. The main-card hosts some huge bouts, with Charles Oliveira and Islam Makhachev going head-to-head for the vacant UFC lightweight title.
Aljamain Sterling will put his UFC bantwamweight title on the line in the co-main event when taking on T.J. Dillashaw. Despite the other three bouts having no belts on the line, they're all just as exciting.
Sean O'Malley will be looking to cement himself as a genuine UFC title contender when taking on the number one ranked Petr Yan this weekend. The Russian is by far O'Malley's toughest test and will likely lead to a title shot if the American passes the test.
Two more potential title challengers will also be looking to make a statement, with Beneil Dariush and Mateusz Gamrot competing in a hyped lightweight bout. The first fight on the UFC 280 main card takes place in the women's flyweight division, with Katlyn Chookagian taking on Manon Fiorot.
