The UFC has filled the holes in the co- and main event for UFC 152 in Toronto on September 22.

Taking the headline bout will be Joseph Benavidez and Demetrious Johnson. The two will meet in the finals of the first-ever UFC flyweight tournament. The winner will leave Canada as the UFC flyweight champion.

In the co-main event, middleweight contenders Michael Bisping and Brian Stann will collide in a bout sure to provide fireworks.

Bisping and Stann have been seeking a match with each other for several years now, and the two called each other out recently. This fight could also go a long ways in determining the next challenger to UFC middleweight champion Anderson Silva.

Benavidez has been sitting on the sidelines due to a scoring error in the first Johnson-Ian McCall match. The two were forced to fight again, with “Mighty Mouse” coming out on top.

The two fights are added to an announced Rory MacDonald-BJ Penn bout that will see “The Prodigy” return from retirement to face the rising prospect from Canada.
