Former lightweight champion Anthony "Showtime" Pettis will officially make his debut at featherweight at FOX UFC Fight Night in Vancouver on Aug. 27.

Pettis will face No. 7-ranked featherweight Charles Oliveira on the new card just confirmed by UFC officials to FOX Sports on Wednesday.

The new event will air live on FOX on Saturday night, Aug. 27, from the Rogers Arena in Vancouver, British Columbia, Canada.

"Anthony Pettis is dropping down to featherweight to face Charles Oliveira and "Showtime" is always a highlight reel guy and so is Oliveira. That's going to be a great fight. We haven't even announced the main event yet and the main event's going to be very interesting too," UFC executive vice president Tom Wright told FOX Sports on Wednesday.

"I've seen both these guys fight live and they don't know how to have boring fights. It's really going to be interesting to see what (Pettis) does at featherweight and you know how the UFC is. We don't give anybody a mulligan or a give-me so his debut is against one of the best in the division. It's going to be awesome."

Pettis will move down to featherweight after a long career spent fighting at 155 pounds, where he was both the UFC and WEC lightweight champion in the past.

He'll get no easy test facing Oliveira as the Brazilian comes into the fight following a blistering quick finish over Myles Jury in his last bout, which moved him to 4-1 over his past five contests.

A middleweight matchup between Garreth McLellan and Alessio Di Chirico has also been added to the card.

"This will be the first big FOX card that other than the (Alexander) Gustafsson against (Anthony) 'Rumble' Johnson fight out in Sweden, this will be the first time it's been out of the United States. Vancouver's a world-class city. We've got great fans out there. This will be our fourth event (in Vancouver) so we're really excited about it and can hardly wait," Wright said about the card.

"I think the fans are going to see a great card. Dana (White), Joe Silva and Sean Shelby always put together great cards but for big FOX, I think it's going to be memorable."

Wright also teased that Canadian fans might want to keep an open schedule for the remainder of 2016 as well because another big event may be headed there before the end of the year.

"Once this event on August 27 is over, there's still four months left in 2016," Wright said. "If Canadians are looking forward to another big event, they should stay tuned."
