The Celtic Warriors fighter upset American Antoine Douglas in the seventh round of their WBO Inter-Continental title fight in Canada.
The chief support bout on the Saunders-Lemieux card at Place Bell in Montreal, O’Sullivan outlasted his touted foe and brought an end to the contest in the seventh round.
The Mahon man drove Douglas to the ropes and unleashed hooks that put him down heavily. Douglas [22(16)-2(2)] rose on very unsteady legs and the bout was waved off to seal a sensational win for Spike.
