Former world champion and Olympic gold medallist James DeGale says he plans to return to boxing after six years by first competing in the controversial Bare-Knuckle Fighting Championship. Thanks to the power of social media, the controversial sport is one of several extreme combat sports on the rise. DeGale's once bitter rival and fellow former world champion George Groves tells Lee James and Ade Adedoyin that he sees the appeal for former professional boxers, but doesn't believe the likes of bare-knuckle boxing and Power Slap will one day overtake traditional fight sports like boxing.
