Main event: MacDonald vs. Saffiedine

A UFC welterweight bout between Rory MacDonald and Tarec Saffiedine will serve as the main event of a UFC Fight Night event on Oct. 4 in Halifax, Nova Scotia.

UFC officials announced the welterweight contest Thursday. The event will take place at Halifax Metro Centre and air on Fox Sports.

MacDonald (17-2) will look to potentially solidify a UFC title shot against Saffiedine. The 25-year-old Canadian is 8-2 in the UFC and coming off a dominant unanimous decision win over Tyron Woodley at UFC 174 in June.

Fighting out of Tristar Gym in Montreal, MacDonald's losses have come to Carlos Condit and Robbie Lawler. Lawler (24-10) is expected to fight Johny Hendricks for the UFC title in early 2015.

Saffiedine (15-3) scored his first UFC victory in a unanimous decision against Hyun Gyu Lim at a UFC Fight Night in January. He was scheduled to fight Jake Ellenberger at UFC 172 in April, but was forced from the card due to injury.

A former Strikeforce champion, Saffiedine will ride a five-fight win streak into the contest. All five wins have come via decision.

ESPN.com ranks MacDonald and Saffiedine the Nos. 3 and 10 welterweights in the world, respectively.

The 170-pound main event is currently the only fight scheduled for the Oct. 4 card. It will mark the UFC's first trip to Halifax.
