UFC 203: Miocic vs Overeem is an upcoming mixed martial arts event produced by the Ultimate Fighting Championship (UFC) that will be held on September 10, 2016 at the Quicken Loans Arena in Cleveland, Ohio

This will be the first UFC event in Cleveland.

The event is expected to be headlined by a UFC Heavyweight Championship match with current champion Stipe Miocic defending the title 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 is scheduled to take 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 Punk’s need for training time. He will make his debut against Mickey Gall in a welterweight bout.
