Anthony Joshua will defend his World Heavyweight titles against Kubrat Pulev at the Principality Stadium in Cardiff on October 28, live on Sky Sports Box Office. Joshua returns to the ring following his epic battle with Wladimir Klitschko at Wembley Stadium in April where the Brit added the WBA strap to his IBF belt in an enthralling contest with the future hall-of-fame legend, climbing off the canvas to record an 19th straight KO win in front of a record-breaking crowd in London. The unbeaten Olympic gold medal hero will now tackle his IBF mandatory Pulev, the Bulgarian rated number one in the IBF facing his second world title challenge having faced Klitschko for the IBF title in November 2014.
