Khan has been marred by a weak chin as a boxing professional, which left him susceptible to Crawford’s sneaky punching power and world-class accuracy.
But when Crawford landed an accidental low blow, which appeared to hit Khan on his right leg, he was deemed unable to continue the fight.
During the post-fight press conference, Khan said he was advised by his trainer Virgil Hunter to stop fighting.
“I saw Amir Khan’s face, he was shaking his head and I was getting disappointed the whole time,” said Crawford, who knocked down Khan in round one of the fight and was dominating since. “I knew that he was looking for a way out.’”
Khan, who surprisingly joined Crawford minutes later at the presser, denied the champion’s claim while seated a few feet to his left.
“I would never quit, I would rather get knocked out,” Khan said.
“You didn’t quit?” Crawford interrupted. “Tell the truth.”
Crawford also said he was confused because he contests that the low blow was just a punch to Khan’s thigh.
“You quit with a shot in your leg?” Crawford asked.
But on Sunday, Khan claimed he was urinating blood from the punch he took to the groin.
Because Crawford was his typically overwhelming self, many aren’t disputing the final result, leaving him open to bigger challenges on the horizon, including a desired date with IBF World Champion Errol Spence (25-0, 22 KOs).
Along with Barclays Center mainstay and WBA Super World Champion Keith Thurman (29-0-1, 22 KOs), Spence and Crawford are viewed as the best of the loaded weight class.
But will the fight happen? Probably not. Spence is promoted by Al Haymon, and Crawford is promoted by Top Rank and Bob Arum. Neither side is eager to work with one another, and this is boxing after all. Disappointment is a requirement, not an option.
Elsewhere on the card, Brooklyn native Teofimo Lopez (13-0, 11 KOs) stopped Edis Tatli (31-3, 10 KOs) with a body shot in round five. Olympic bronze medalist Shakur Stevenson (11-0, 6 KOs) decisioned Christopher Diaz (24-2, 16 KOs), and Puerto Rican star Felix Verdejo (25-1, 16 KOs) outpointed Bryan Vasquez (37-4, 20 KOs).
Highlights from the undercard included Brooklyn-born Bronx resident Edgar Berlanga, a new Top Rank signee (10-0, 10 KOs) knocking out Samir dos Santos Barbosa (37-16-3, 26 KOs) 46 seconds into the first round. It was Berlanga’s tenth consecutive first round knockout.
And Brooklyn’s Frank Galarza (20-3-2, 12 KOs) lost by TKO to undefeated Dominican rising star Carlos Adames (17-0, 14 KOs).
