Savannah Marshall reclaimed her place at the summit of women's boxing as she beat Franchon Crews-Dezurn by majority decision to become undisputed super-middleweight champion of the world and open the door to a potential rematch with Claressa Shields, who watched on from ringside in Manchester.

Marshall out-manoeuvred and out-classed her American opponent in a gritty, gruelling and, at times, messy battle as she fought for the first time since suffering her first professional defeat to Shields in October's historic grudge match at The O2.
