Lawler to face MacDonald

Lawler, who claimed the title courtesy of a split decision victory over Johny Hendricks in December, was originally scheduled to fight Hector Lombard in Montreal in April, but the fight was cancelled after it was revealed that Lombard had failed a drug test.

As a result, Lawler will now come up against MacDonald at UFC 189 at the MGM Grand Garden Arena.

The fight will be the co-headline event, with the featherweight title fight between Jose Aldo and Conor McGregor having previously been announced as the headliner.
