London's calling for light-heavyweight king Artur Beterbiev. He defends his belts against big-punching British challenger Anthony Yarde at the OVO Arena Wembley on Saturday, January 28. “I never back down from a challenge, and Anthony Yarde is a top contender who asked for this fight. I look forward to fighting in London for the first time since the Olympics,” Beterbiev said. “Yarde called me ‘slow’ after my fight with Joe Smith Jr., but slow and steady wins the race. And on January 28, I will win in London.”
