Jon Jones has suffered an ankle injury in training that has seen his proposed UFC 178 fight with Daniel Cormier moved to next year.
The undefeated light heavyweight champ has suffered a 'leg injury' per MMAJunkie.com, with rumours on Twitter saying that it's his ankle that has forced him out of the fight.
It puts to bed perhaps the most hyped bout of the year, with Jones and Cormier's verbal back and forth - as well as their on-stage brawl - earning the two fighters huge interest.
What next for the UFC?
The move will have serious repercussions for the UFC and, per Ariel Helwani, the fight will be moved to January 3 2015 - currently scheduled to be UFC 182.
The UFC have opted to move the flyweight championship clash between Demetrious 'Mighty Mouse' Johnson and Chris Cariaso from the UFC 177 undercard to the main event of UFC 178.
The 178 card has a stacked undercard but with this announcement, it's likely to go from the best selling PPV event this year to one of the lower ones, striking middle of the pack at best due to fans not buying lower weight class main events as well as others.
Inside the light heavyweight divisio, though, Alexander Gustafsson will be perhaps the most annoyed.
The Swedish fighter was looking forward to a fight early next year against the winner of Jones-Cormier, however, it's appearing more likely than ever that he'll be forced to defend his number one contendership.
'Blessing in disguise'
Cormier has wasted no time in going after the champ, telling Ariel Helwani of MMA Fighting that the injury was a 'blessing in disguise' for Jones.
Although he did voice some concerns over Gustafsson getting his shot back - which he gave up after he too suffered an injury - Cormier has been reassured by the UFC that it's his time.
The hype surrounding the two always felt like it would have a let down somewhere, but most expected it to be on fight night.
Instead it's happened six weeks before the event and now we have to wait another five months before the two will clash, although that's five more months for these two fighters to trade verbal jabs back and forth across the media.
So perhaps it is a blessing in disguise, not just for Jones, but also for fight fans and the UFC. This could be the greatest event to kick start a year and could make 2015 the year that the UFC takes that next step.
