The UFC are scrambling to find an opponent for light-heavyweight challenger Anthony 'Rumble' Johnson to salvage the main event at UFC 206.
Plans for the card in Toronto have be dealt a disappointing blow as Daniel Cormier has been forced to withdraw due to a partially torn groin.
The champion was set to defend his belt against the heavy-handed Johnson but will no longer be able to compete.
According to MMA Fighting, It is understood that the intention is to replace Cormier and find a suitable opponent on relatively short notice.
This is familiar territory for the UFC who have been forced to change their plans 33 times for the main or co-main event.
Injuries are part and parcel of the sport particularly with competitors pushing their bodies to the limit in preparation for a fight.
That said, the trend for major draws at huge events is considered to be disruptive from a business perspective.
This is not the first setback for UFC 206 however, as Tim Kennedy's bout against Rashad Evans was shelved after the Ontario Athletic Commission refused to license Evans based on a medical issue.
Though occasionally injuries to the major protagonists of a Fight Night have led to the event being cancelled, that is not expected to be the case here.
There are still a number of stellar match-ups on the card to look forward to, including Anthony Pettis vs Max Holloway and Donald Cerrone vs Matt Brown.
