Whyte will regardless remain at world-level as one of the division's leading contenders and a likely future challenger to Joshua, but if he is forced to wait could struggle to maintain the impressive momentum he has built.
Wembley has been booked for April 13 but Joshua is yet to nail down an opponent, although promoter Hearn suggested Whyte - angered by Joshua's assertion that he was third in line behind Wilder and Fury - could now be in pole position.
What remained of the 19,000 sell-out O2 crowd voiced their frustration before Whyte stormed back to his dressing room.
"I hurt him in the first round and I wanted to go after him but I knew I had to take my time", said Whyte afterwards. My careers needs to progress.
The end of the fight was chilling, Whyte knocked Chisora out cold with a left hook in the 11th round.
"The clock is ticking". I'm 30, I'm about to hit my prime now.
He had hoped subsequent victories over former world champions Lucas Browne and Joseph Parker would earn him another chance.
Chisora, who can be forgiven his fashion faux pas of wearing sunglasses indoors, can be seen slumped across a sofa before Whyte approaches him with a handshake.

Flynn sentencing delayed after judge flags 'very serious' crime
The judge - who has a well-deserved reputation as both tough and fair - made several fundamental errors right at the outset. The judge agreed to postpone sentencing upon request from Michael Flynn's lawyers at court in Washington DC .
There was no need for the judges in the rematch, however, with Chisora laid out by a left hook that negated the need for referee Marcus McDonnell to even bother issuing a count.
Then Whyte sent him crashing to the canvas where he lay motionless.
"So if the Whyte fight gets made I don't want to hear any boos", said Joshua.
On December 1st, Fury and Wilder would go the distance in a split-decision draw that would cause the immediate call for a rematch between the two.
"Whyte is the favourite, but Chisora is very tough", Higgins noted.
Despite claims in some quarters over Fury's unavailability for a rematch, Wilder insists he will be fighting Fury next.
"If Deontay Wilder ain't serious and he's gonna fight Tyson Fury and he doesn't want to become undisputed, Dillian, you'll get a shot". Him and "AJ" is a brilliant fight.
