Jessica Camara clashed with Caroline Dubois after weighing in on their WBC lightweight world title fight.
The Canadian challenger bored forward before being held back by Dubois as Camara snapped: “Don't disrespect me!” after the two were separated.
Dubois will make his first defense of the WBC Championship, live, on Saturday Sky Sports.
The champion warned: “This is not the end for me. This is just the beginning.
“She's a pebble in my shoe right now and I have to get her out of the way.”
WBC lightweight champion Dubois retains Camara
But Camara replied: “She will not do (anything).
“I have what it takes to do it and that's what I'm going to do.
“She believes in herself. I believe in myself,” she added. “I felt a little disrespected today so I just showed her what she had.”
Dubois, however, took it all as a sign of weakness. “I see fear to be honest. I see a lot of fear, I see a lot of nerves,” she said afterwards.
Both fighters entered the world championship bout at the Canon Medical Arena in Sheffield, with Camara 9st 8lbs and Dubois 9st 8lbs 5oz. The fight, with an added edge of ferocity, is on.

Callum Simpson and Steed Woodall also made weight in their British and Commonwealth super-middleweight title bout, the former weighing in at 11st 13lbs and the latter at 12st exactly.
“I'm ready for a 15-round war if I have to,” Woodall warned the champion. “I'm in phenomenal shape, I'm ready.
“Records are for DJs, it doesn't mean anything to me,” he continued. “All that matters is me and Callum in the ring.”
Hugely popular in his home town of Barnsley, Simpson's supporters were heard at the Cutlers Hall weigh-in.
“It's not just my journey, it's our journey, they've supported me from day one,” beamed Simpson. “It's a dream come true.
“It doesn't matter the challenger, the champion, my mindset is always the same, to become the best I can be,” he continued.
“I believe the best Callum Simpson beats the best Steed Woodall.”
“I worked very hard to get these (titles), I will work very hard to keep them… They will stay in Yorkshire.”

“The cruiser category is popping up so there's a lot to like.”
Forrest, a knockout in imposing condition, maintained the same intensity, declaring, “He can say what he wants, but don't blink because he's being sprayed.”
