LOS ANGELES, United States — Conor McGregor will return to the Ultimate Fighting Championship Octagon for the first time in five years when he takes on Max Holloway in a non-title rematch on July 11 in Las Vegas, UFC said Saturday (Sunday Manila time). Ireland's McGregor, a former two-weight champion and still one of UFC's most famous and bankable fighters, hasn't fought since suffering a broken leg in a loss to Dustin Poirier on July 10, 2021.
