UFC 152: "Jones vs. Belfort" is all set to pop off tomorrow night (Sat., Sept. 22, 2012) from the Air Canada Centre in Toronto, Ontario, Canada, featuring a light heavyweight championship showdown pitting reigning division king Jon Jones against former 205-pound straphanger Vitor Belfort.

Also on tap for the mixed martial arts (MMA) promotion's return to the "Great White North" is another championship battle, this one to crown the promotion's first ever flyweight champion. Joseph Benavidez and Demetrious Johnson will contest for that title.

And don't forget about Michael Bisping vs. Brian Stann.

Before we can get to the good stuff, however, every one of the competitors on tomorrow night's fight card had to hit the scales to make sure they weren't carrying any extra baggage. Charles Oliveira was just a tad heavy but his bout with Cub Swanson will go without issue.

Here we go.
