Based in Dubai for the final part of his camp before his UAE debut, Conor McGregor did presumably what any transcendent superstar would do to journey to Abu Dhabi. He hopped aboard a luxury yacht. The Irishman posted pictures from the deck on Monday, with one looking out at the newly opened Etihad Arena. McGregor makes his long-awaited comeback to the octagon there on Sunday. The former two-division champion, who hasn’t fought competitively since last January, takes on Dustin Poirier in the headline bout at UFC 257, which brings down the curtain on Fight Island Triple Header in the capital. True to form, McGregor has arrived in Abu Dhabi his own style.
