Carl Froch knocked out George Groves in their rematch at Wembley Stadium on this day in 2014 as the Nottingham fighter retained his WBA and IBF super-middleweight titles.

Froch added to his victory in the initial bout in Manchester the previous November, in which he had recovered from a first-round knockdown and terrible start to stop Groves controversially in the ninth.

This time he finished the contest with a breathtaking eighth-round punch which knocked Groves out in front of a crowd of 80,000.

Froch said afterwards: “I showed tonight why I’m a four-time champion of the world, why I’ve defended my world title 13 times on the spin.

“I am amongst the best fighters in the world – that’s who George Groves was in there with tonight.

“The finish of that (fight) showed why I’ve mixed with the elite for many years and how hard it is to get to that level.”

He added: “I am feeling unbelievably elated. This is the best moment in the history of my boxing career.”

Groves made a solid start to the contest which began cagily, with neither fighter wanting to give anything away. Froch was patient, waiting for his opening and Groves struggled to keep pace as the fight wore on.

“I knew it was only going to take a couple of big right hands to the chin and I timed it perfectly,” Froch said.

Groves said: “It’s boxing and fair play to Carl, he caught me and I went down. Obviously I felt I was doing very well in the fight, I was in my groove and I was boxing well but it’s boxing.

“I’ll come back bigger, better and stronger. Ultimately I feel like I let myself down but congratulations to Carl, fair play, he got the punch.”

It proved the last fight for Froch – aged 36 at the time – before retirement, with him hanging up his gloves with a professional record of 35 bouts, 33 wins and two defeats, 24 of the victories coming by knockout.
