White confirmed the 115-pound bout to ESPN on Monday. The UFC Fight Night event will take place at Scotiabank Saddledome.
It's another highly ranked bout for the Canadian event, which already features a featherweight fight between Jose Aldo and Jeremy Stephens. The UFC has not yet announced a main event, however sources have informed ESPN a lightweight fight between Eddie Alvarez and Dustin Poirier is one potential option.
White has been promising the city of Calgary an event for years. The UFC has made one previous trip there in 2012, but fighter injuries greatly impacted that event.
Jedrzejczyk (14-2) is coming off back-to-back losses to current champion Rose Namajunas. The Polish strawweight is still considered one of the best fighters in the world, and she felt she did enough to win their five-round rematch at UFC 223 in April.
Prior to the pair of losses to Namajunas, Jedrzejczyk was 8-0 in the UFC and one win away from tying Ronda Rousey's all-time female record of six consecutive title defenses.
Torres (10-2) is coming off a decision loss to Jessica Andrade in February. Fighting out of Colorado, Torres had won three in a row prior to that defeat.
