Claressa Shields says she is yet to decide whether to stay at the heavyweight division despite recording an explosive second round knockout win over WBC women’s heavyweight champion Vanessa Lepage-Joanisse.

Shields (15-0, 3 KOs) made history yet again last Saturday night at Detroit’s Little Caesars Arena when the reigning undisputed middleweight titlist moved up two weight classes to dethrone WBC Women’s heavyweight champion Lepage-Joanisse (7-2, 2 KOs) of Canada.
