After Crawford hit Amir Khan (33-5, 20 KOs) with an accidental low blow in the sixth round, Khan's trainer Virgil Hunter called for the end of the fight, handing Crawford (35-0, 26 KOs) a controversial technical knockout win at Madison Square Garden in New York City.
After the bout, Crawford called out IBF world welterweight champion Errol Spence Jr., per SportingNews.com's Andreas Hale:
Late in the first round, Crawford stunned the contender with a chopping counter right hand followed by a left hook for good measure.
Slipping Khan's jab and countering with the lead right proved to be a simple but effective strategy for Crawford.
Khan had a couple of positive moments at the end of the fifth, timing a left hook and landing a couple of jabs flush to the chin.
