Warren made the declaration at a press conference on Wednesday and sent out subsequent correspondence to the media outlining the arrangement with Fury, which Hennessy has now stated is yet to reach the contract exchanging stage.
“These reports are not true,” Hennessy stated.
“We have had a verbal offer from BoxNation for Tyson to appear on three of their shows, but as yet have not received any contract to look at and consider. Until something is agreed in writing and signed into, myself, Peter Fury (Tyson’s uncle and trainer) and Tyson, we are still keeping our options open.
“We were told it would be 48 hours before we even receive any paperwork to look at and we are still awaiting any such communication.”
Dereck Chisora is headlining the London show next month, which Warren hopes Fury will co-feature on with a view to the two heavyweights staging a rematch at an outdoor venue in June.
‘Del Boy’ was beaten on points by Fury when weighing in grossly over his trim new limit in the summer of 2011, but has since shown form that suggests Chisora is ready for another crack at world title.
The 30 year-old lost out in his previous attempt to claim the WBC belt from the now retired Vitali Klitschko and Warren is aiming to pit Chisora and Fury together in a possible eliminator to face his younger brother Wladimir.
