Simon Brown dazed welterweight Shawn O’Sullivan with a looping left hand late in the second round and then unleashed a flurry of punches in the third, stopping the previously-unbeaten Canadian Olympian.

Referee Fern Chretien halted the scheduled 10-round bout at 2:37 of the third round with O’Sullivan standing glassy-eyed in his corner, gloves hanging limply by his sides as Brown showered him with combinations.
