Sports streaming service DAZN, which launches in the United States on Monday, has stocked up on combat sports rights by making deals to stream Matchroom Boxing events, all three second-season World Boxing Super Series tournaments and Bellator MMA. On Thursday it added the super middleweight final of the first season of the World Boxing Super Series. The fight matches 168-pound world titlist George Groves (28-3, 20 KOs), who is making his third defense, against British countryman Callum Smith (24-0, 17 KOs) for Groves’ belt and the Muhammad Ali trophy on Sept. 28. The stream is scheduled to begin at 4 p.m. ET from the Indoor Sports Hall at King Abdullah Sports City in Jeddah, Saudi Arabia. DAZN will offer boxing events on three consecutive weekends with the Anthony Joshua-Alexander Povetkin heavyweight world title card Sept. 22, the WBSS card on Sept. 28 and the Oct. 6 Matchroom card in Chicago headlined by the Jessie Vargas-Thomas Dulorme welterweight bout.
