"My world has been put into perspective in the last four weeks, it's been the toughest four weeks of my family's lives and I will dedicate my victory on 17 December to my late brother-in-law".
The pair will fight for a second time some nine months after Bellew pulled off an upset at the same venue.
The British fighters faced off at the O2 London back in March, when Liverpool native Bellew claimed victory by an 11th-round TKO after Haye had fought on with an Achilles injury picked up in the sixth.
The bout caps a stellar year of boxing on Sky Sports, which has included Andre Ward v Sergey Kovalev, James DeGale v Badou Jack, Carl Frampton v Leo Santa Cruz as well as major moments on Sky Sports Box Office including Joshua v Klitschko and Mayweather v McGregor.
"Will Bellew be able to dig that deep a second time and prevail as an underdog again? Another loss to me closes the curtain on the Hayemaker", he said in press release announcing the fight.

'I wont be the favourite, it's the fat guy against the body lovely David Haye so I'll always be the underdog.
Haye - the heavyweight champion between 2009 and 2011 - has rebuilt both his body and his team since the loss to Bellew, with Ismael Salas taking over from Shane McGuigan as his trainer.
Bellew's promoter, Eddie Hearn, added: "Tony had plenty of options on the table but this was the biggest fight out there and one he wants to end once and for all". "On March 4, the script was thrown out the window and the unpredictability of sport revealed itself in its most raw form", he said. Without question, [Bellew] showed great heart, grit and determination to weather the early storm.
"I've been training every day for over six months".
"I will have the exact same attitude I had going into the first fight - win at all costs", said Bellew. I already feel fitter, stronger and more athletic than I did for our first showdown!
