Joseph Benavidez and Demetrious Johnson will look to become the promotion's first 125-pound champion in the main event of UFC 152. UFC officials confirmed the news Friday in addition to a middleweight tilt between Michael Bisping and Brian Stann.

The UFC added the flyweight division in early 2012, kicking off a four-man mini tournament to determine the first title contenders.

Benavidez (16-2) earned his way to the title fight with a second-round TKO victory over Yasuhiro Urushitani in March. The former bantamweight has lost only two fights in his career; both to 135-pound champion Dominick Cruz.

Johnson (15-2) took a slightly longer route. He originally was awarded a decision over Ian McCall in March, but an error on the scorecards revealed the contest was actually scored a draw.

An immediate rematch was booked for June, when Johnson claimed a unanimous decision.
