UFC 294 was set to be one of the biggest fight cards of the year, and it is arguably even bigger after undergoing two major, late changes.

In the main event, Islam Makhachev defends the lightweight title against featherweight champion Alexander Volkanovski, whom he narrowly outpointed in February, with the latter stepping in for the injured Charles Oliveira.

Makhachev submitted Oliveira 12 months ago to win the vacant lightweight belt, and their highly-anticipated rematch was scheduled to take place this weekend in the same venue – the Etihad Arena in Abu Dhabi – until a severe cut ruled out the Brazilian. In steps Volkanovski, however, for another tantalising rematch.
