Bookmakers will be hoping odds-on favourite Carl Froch can retain his IBF and WBA super middleweight titles on Saturday night, with punters piling into George Groves in their masses.
Groves was given odds of 10/3 the last time the pair met, with Froch satisfying his price of 1/4 by forcing a ninth-round stoppage, albeit in controversial fashion.
The impressive performance Groves put on in the first fight has convinced punters of his value at 5/4, with the Londoner to win in round three the most popular choice in the individual round betting at 33/1.
Froch is not completely friendless in the betting though, with his backers largely behind a seventh-round stoppage win at 18/1, while he's also popular at 5/2 to win in rounds 7-12.
'The Cobra' climbed off the canvas to stop Groves first time around, something Sky Bet make 9/2 to happen once more, while an exact carbon copy of Froch to be knocked down in the first but win in the ninth is a massive 50/1.
Sky Bet's Dale Tempest said: "It's all Groves in a fairly one-sided book, which has surprised us somewhat, so it's an old fashioned case of the bookmakers verses the punters.
"We were hoping for a more balanced trend in the betting for what most people see as a real 50-50 fight, but I guess the value in 5/4 shot Groves is too tempting for most.
"We'll be behind Froch on the night but if Groves does manage to pull off the upset, then it's quids-in for him and our customers.
"Either way, it's great for the industry as the main event is on track to be the most popular fight we've ever taken bets on."
