Groves is waiting for his opening. Froch walks into a right hand. The challenger shades the second round.
Now it's Carl Froch on the front foot. Groves, a classic counter-puncher, hits the Cobra to the side of the head with an uppercut.
The pair come together and start trading, with the referee splitting them up and issuing a warning to both men. Groves smiles.
Both fighters land a long-range shot which rocks the other man's head back.
Rob Allen: Something fantastic about listening to 5 live boxing... Reminds me of Bruno v Tyson all those years ago....top stuff...

"There was was nothing in it at all. It was very close it could have gone either way."
Steve Bunce
BBC Radio 5 live boxing pundit
"That was a round from two men still plagued from their memories of the first encounter. It was interesting that he last 30 seconds Carl did get closer and did try and drop that right hand over."
Froch corners Groves at the end of the round and wears a jab. Very little in that opening round.
It remains cagey early doors but it's George Groves on the front foot. Both men stay at range.
Carl Froch wears a couple of jabs to the face. Some early reddening on his face.
Groves leads with a right but doesn't connect. A bit of shadow boxing in the first minute.
Ding ding ding. Let's go.
BBC Radio 1 Xtra DJ Trevor Nelson:, external This is ridiculous. The crowd size is Ali v Frazier yet it's Froch v Groves. British boxing is back.
Drink of choice in hand? Tick. Snacks? Tick. Two world-class boxers? Tick. 80,000 spectators? Tick. Free full-fight commentary on BBC Radio 5 live? Tick. Let's do this thing.
The words we've all been waiting to hear since Howard Foster stepped in a little early in November..."Let's get ready to rumb-l-l-l-e-e!"
James: Groves is ready to go! Come on Saint GG
Chris Mooney: No idea who will win but hope tonight inspires the next generation of British boxers. Want more nights like this.
"It's the rematch the world has been waiting for," declares Michael Buffer as he ticks a few boxes. We now know who is sponsoring the contest, who is judging it and who is refereeing it. New Yorker Charlie Fitch in case you were wondering about the ref!
ChrisJamesPeet:, external I believe this pugilistic duel will be settled fleetingly by Mr Froch and all hyperbolic ballyhoo will be rendered extraneous.
LiamBurnell:, external C'mon the Cobra! Show him how it's done.

"For Carl Froch, the advantage of course being the defending champion is that he comes into the ring second. George Groves had to stand there about 10 minutes, nervous. He had to stand there and watch what Froch is doing."

Carl Froch steps between the ropes while his entourage holds aloft his two world titles. It's easy to forget what is at stake - this is more than a domestic leveller. This is the big time.
