See Terence Crawford's reaction to Shawn Porter's brutal KO just seconds before.

TERENCE CROWFORD was shocked to hear Shawn Porter had won their welterweight match.

Bud won a thrilling tenth-round TKO win over the former IBF champion 147lb last weekend to keep his WBO title.

He was stunned by the assessment of his corner moments before he stopped Showtime.

Southpaw was told by Coach Brian McIntyre: "Hey! This fight is close. Porter's up. {This is This is round] ten."

Crawford, perplexed, replied: "Okay. I'm up? He's up?"

McIntyre was fired up and replied, "C'mon Bud, pay attention. Round ten is coming up. "We got to double in as he was."

Crawford stood up and said, "They say they up, they say that he up." Ten coming up?"

Crawford, laser-focused, asked again: "He's up?" Okay."

Crawford rocked Porter with a stunning counter right hand, just a minute after his coach's passionate plea for speed. Then he put him on the canvas with the left hook.

Porter, furious, repeatedly hit the canvas while the referee gave the count. He won.

Kenny, the father-to-be, had had enough and decided to let go of his son's punishment.

Crawford was overcome with joy and burst into primal screams as he celebrated his biggest win of his career.

Crawford, 34, is now aiming for a long-awaited fight with Errol Spence Jr., unified welterweight champion.

He stated that Spence was present at his fight during the post-fight press conference.

"That boy said that he wouldn't be attending my fights. Now he's at mine.

"You can see what I did, compared to his."

He said: "Who is number one in the welterweight category now?"

"I've been calling out to him all day. Perhaps I'll get up to 154. Perhaps Spence will fight me if he gets his tail out from his butt."

Crawford will face Spence, but without the support of Top Rank Boxing's former promoters.

He stated, "I'm pretty certain my decision has been made already.

"Bob could not secure me the Spence fight while I was with him.

"So, how will he secure me the Spence fight if I'm not with Him?"

"I am moving forward with my career now."
