Watch as #TysonFury #MannyPacquiao and Sugar Ray Leonard surprise Bob Arum and Sing Happy Birthday. Next Up for Top Rank Boxing, WBC/IBF unified light heavyweight world champion Artur Beterbiev moved to Montreal nearly a decade ago to embark on his professional journey following a pair of Olympic berths for his native Russia. Sixteen fights into his career, he will return to his adopted hometown for the first time as a world champion. Beterbiev, boxing’s only world champion with a 100 percent knockout rate, will defend his world titles against WBC No. 1 contender and 2012 U.S. Olympian Marcus Browne on Friday Dec. 17 at the Bell Centre in Montreal. Beterbiev-Browne will headline a loaded world title tripleheader streaming live and exclusively in the United States on ESPN+.
