Last night's UFC 199 pay-per-view event was jam-packed with interest.
In the main event, middleweight champion Luke Rockhold was stunned by Michael Bisping with a first round KO.
There were also two major announcements. Conor McGregor's rematch with Nate Diaz was confirmed for UFC 202 on August 20th.
There will also be a return to the Octagon for a fan favourite - Brock Lesnar. It's four and a half years, since Lesnar, now 38, fought in the UFC.
His last fight was a loss to Alistair Overeem at UFC 141 in December 2011.
Lesnar is currently under contract to the WWE. However, the WWE announced last night that it is allowing Lesnar a 'one-off opportunity' to fight on July 9th.
Brock Lesnar remains under contract to WWE, however, he has been granted a one-off opportunity to compete at UFC 200. Following this milestone event on July 9, Brock will return to WWE for SummerSlam on Sunday, August 21, live on WWE Network.
Who Lesnar will fight is yet to be confirmed, though there are rumours it could be Mark Hunt.
The UFC told Aussie Mark Hunt to stay in shape... Could he be the one to face Brock Lesnar at #UFC200? @ufc @markhunt1974

Whoever Lesnar fights, it will be the co-main event on an already stacked card. The main event on the night is a rematch between current light heavyweight champion Daniel Cormier and interim champion Jon Jones. Other fights on the night include Miesha Tate's first title defence against Amanda Nunes and an interim featherweight decider between Jose Aldo and Frankie Edgar.
