Unfounded rumours of an injury hampering Haye’s build-up have seen the two-weight world champion head out from 1/7 to 1/6 on.
Bookie Betway is also offering even-money on post-fight embrace.
Betway’s Alan Alger, said: “Rumours of David Haye’s achilles niggle have had the betting markets wavering a bit. Though Tony Bellew is still the definite underdog, he’s been backed into 4/1 from 5/1 in the last 12 hours.
“Haye was solid at 1/7 for some time, but punters are clearly thinking the bigger odds on a fit Bellew are value and the Bermondsey boy has drifted out to 1/6.
“We’ve got a number of specials relating to the big night, offering 1/4 for the squabbling pair to touch gloves before the fight and evens they embrace after the final bell.”
