Next month's UFC on FOX 7 event has two new additions.
They include flyweights Joseph Benavidez (17-3 MMA, 4-1 UFC) vs. Darren Uyenoyama (8-3 MMA, 2-0 UFC), as well as bantamweights Francisco Rivera (9-2 MMA, 2-0 UFC) vs. Hugo Viana (7-0 MMA, 2-0 UFC).
UFC officials today announced the fights.
UFC on FOX 7 takes place April 20 at HP Pavilion in San Jose, Calif. The main card airs on FOX following prelims on FX and Facebook.
It's not clear where Benavidez vs. Uyenoyama and Rivera vs. Viana will be placed on the lineup.
Benavidez, a former WEC title challenger, has won five of his past six fights, and the lone loss came in a fight with Demetrious Johnson for the inaugural UFC flyweight title. However, the Team Alpha Male fighter recently rebounded from the title loss with a decision victory over Ian McCall.
He takes on California-based fighter Uyenoyama, who's posted wins over Norifumi Yamamoto and Phil Harris since his arrival in the UFC. The Harris victory marked the former Strikeforce and DREAM fighter's move down from bantamweight to flyweight.
Rivera, meanwhile, looks to extend his unbeaten streak to six fights following recent UFC victories over Alex Soto and Edwin Figueroa. The California-based WEC vet would be 3-0 in the UFC, but a 2012 win over Roland Delorme was overturned when Rivera tested positive for an over-the-counter stimulant.
Viana, a semifinalist on "The Ultimate Fighter: Brazil," made his UFC debut after the reality show and scored a split-decision victory over John Teixeira. He then dropped to bantamweight and recently scored a knockout victory over Reuben Duran, which marked the first stoppage win of his undefeated career.
The latest UFC on FOX 7 card includes:
Benson Henderson vs. Gilbert Melendez - for lightweight title

Awesome. Don't give Uyenoyama much of a chance though. Rivera vs Viana however = FIREWORKS!
You have Darren Uyenoyama listed twice btw
better not put fucking Clay Guida on the main card.
Is Guida on the main card? 
I doubt Guida is on the main card. 4 fights max for FOX main cards.
it is a solid card up and down, though.
Look at how good this card is, this is gonna be the FX prelims

That's an incredible FX card. Guida haters should tune in because I personally don't give him a chance against Mendes.
Personally I don't care where he is on the card, I just don't think it would be good if he went out and did what he has in last 2 to kick off a Fox card

I personally wouldn't put Guida as the the 'main event' of the FX card to lead into the FOX main card. I think the Benazidez fight would be a better choice.
That main card is awesome.

I personally wouldn't punish Mendes because he's facing someone who doesn't like to fight.
Mendes is gonna smash him anyway.
