Jessica Camara went toe-to-toe with Caroline Dubois after the weigh-ins for their WBC featherweight world title fight.
The Canadian challenger was upset before Dubois stopped her with Camara saying, “Don’t ignore me!” after the two had separated.
Dubois will make her first WBC championship defense on Saturday, live Sky Sports.
The champion warned: “This is not the end for me. This is just the beginning.
“She’s a pebble in my shoe now and I have to get her out of the way.”
But Camara replied: “She won’t do (anything).
“I have what it takes to do it and I will do it.
“She believes in herself. I believe in myself,” she added. “I felt a little disrespected today, so I just let her know what’s going on.”
However, Dubois took all this 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 made weight for their world championship bout at the Canon Medical Arena in Sheffield, with Camara 9st 8lbs and Dubois 9st 8lbs 5oz. The war, with an added edge of ferocity, is on.
Callum Simpson and Steed Woodall also made weight for their British and Commonwealth super middleweight title bout, the former 11-13lb and the latter 12st exactly.
“I’m ready for a 15-round fight if necessary,” Woodall warned the champion. “I’m in phenomenal shape, ready to go.
“Records are for DJs, they mean nothing 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 since day one,” Simpson said. “It is a dream come true.
“It doesn’t matter the challenger, the champion, my mindset is always the same, to be the best I can be,” he continued.
“I believe the best Callum Simpson beats the best Steed Woodall.
“I’ve worked hard to get these (titles), I’ll work hard to keep them… They’ll stay in Yorkshire.”
Another exciting contest on the bill pits undefeated bantamweight Scott Forrest against ambitious Londoner Deevorn Miller.
After weighing in at 14lb 4, exactly the same as Miller, Forrest subjected his opponent to an intense choke.
Smiling afterward, Miller, anticipating his stoppage victory, said: “We’ll see tomorrow. The conversation is over.
“The cruiserweight division is emerging, so there’s a lot to like.”
Forrest, a knockout puncher in commanding form, maintained the same intensity, declaring, “He can say whatever he wants, but don’t blink because he’s splashing.”
Scotland’s Sam Hickey will open the televised bill, in a tricky second pro fight against Lewis Howells.
Ready to make his mark in professional sports, former amateur star Hickey said: “It’s a different kind of energy. This guy is coming for me. I just have to stop him and stop what he can do.”
