Unbeaten American Terence Crawford knocked out David Avanesyan in the sixth round on Saturday to retain his World Boxing Organization welterweight world title.
Crawford, fighting in front of home fans at the CHI Health Center arena in Omaha, Nebraska, sent Avanesyan sprawling with a right hook at 2:14 of the sixth, improving to 39-0 with 30 knockouts.
A former undisputed light welterweight world champion, Crawford made his sixth defense of the title he claimed when he stopped Australian Jeff Horn in the ninth round in June of 2018.
