SSE Arena, Wembley, London - Terri Harper looked sensational as she stopped Norway's Katharina Thanderz in nine rounds to retain her WBC and IBO super featherweight world titles.

Harper clung onto her belts after a thrilling draw with Natasha Jonas at Matchroom Fight Camp back in August, but 'Belter' produced a far more composed performance to ruthlessly halt her mandatory challenger Thanderz.

After the fight, Harper sent a warning to her division rival, WBO world champion Mikaela Mayer.

"I'm buzzing," said Harper. "That's my birthday and Christmas all in one. That's made my year. Obviously having that tough fight with Tasha, there was doubts, and there was wrongs that I needed to put right. We came away and I've worked my butt off. I've just gone out there and breezed it.

"I hurt my hand in the fourth round, I couldn't throw it, and when I did throw it it was painful. I stuck to my jab, kept long and just moved. I knew she got frustrated at one point. She stood in the middle of the ring. I didn't want to look like I was running but there was nothing else that I could really do. I'm happy.

"I caught her with the head, that's probably from me lunging in, accidental. I could see that her nose was troubling her. The sound of her breathing changed. She was getting distracted by the blood. I threw a nice left hook to the body, caught her and I heard her wince. She backed off and I just went for the kill and the ref jumped in.

"I got a few stoppage wins early on in my career so it's nice to get another one. I'm going to say a big thank you to my S&C coach Danny Wilson, he's given me the confidence that I can go through those gears and that I have got the strength. God knows what I'm going to be like after my next camp. I want to fight the best. I'm coming for you Mayer! Slowly but surely we'll get there and I'll be punching you in the face very soon."
