A huge undercard for Joshua vs Breazeale is being pieced together by promoter Eddie Hearn, and the first fight announced is a mouth-watering Super-Middleweights George Groves and Martin Murray in an eliminator bout for the WBA crown.
Both men are hunting a World title shot in the second half of the year, a fourth in the division for Groves and a first at 168lbs for Murray, who boxed three times for a World crown at Middleweight.
