The fight will take place at Scotiabank Centre in Halifax, Nova Scotia.
Original plans had the fight taking place at UFC 208 at Barclays Center in Brooklyn, New York, but the UFC needed a new main event for its televised card one week later. That card recently lost a heavyweight main event between Junior dos Santos and Stefan Struve to injury.
Lewis (17-4) is one of the hottest heavyweights on the roster right now, having won his past five. He has four finishes during the winning streak.
