Description This was the first UFC event in Cleveland.
The event was headlined by a UFC Heavyweight Championship bout between current champion Stipe Miocic against 2010 K-1 World Grand Prix winner and former Strikeforce Heavyweight Champion Alistair Overeem.
The professional debut of former professional wrestler and two-time WWE Champion CM Punk took place at this event. Punk, who signed with the UFC in December 2014, had a delayed debut due to past injuries from professional wrestling that needed treatment and also due to his need for training time. He made his debut against Mickey Gall in a welterweight bout.
