UFC on Fox 7 Promo: Benson Henderson vs. Gilbert Melendez

The UFC has released an official promotional video for UFC on Fox 7, set for April 20 at the HP Pavilion in San Jose, Calif. 

The headlining bout pits UFC lightweight champion Benson Henderson against the last reigning Strikeforce champ at 155 pounds, Gilbert Melendez. 

"Bendo," also a former WEC title holder, is a perfect 6-0 inside the Octagon, though he has yet to put anyone away under the UFC banner. 

Henderson has successfully defended his belt twice, most recently defeating Melendez's Cesar Gracie Jiu-Jitsu teammate Nate Diaz at UFC on Fox 5 in December. 

Meanwhile, "El Nino" has won seven in a row and looked borderline untouchable inside the Strikeforce cage, with the exception of his most recent win over Josh Thomson in May, where he was awarded a controversial split-decision win. 

Also being advertised in the video is the evening's co-main event, where former UFC heavyweight champion Frank Mir squares off against Strikeforce Heavyweight Grand Prix winner Daniel Cormier.

Mir has been on the shelf for just under a year, coming up short in a title bid against Junior dos Santos at UFC 146 in May.

Prior to that loss, Mir had defeated three in a row, including the 2011 "Submission of the Year" when he broke the arm of Antonio Rodrigo Nogueira, a fellow decorated grappler, at UFC 140 in December 2011.

On the other hand, Cormier is a perfect 11-0 as a professional mixed martial artist, most recently scoring an easy TKO win over Dion Staring at the last Strikeforce event in January.

Mir has struggled with strong wrestlers in the past, such as Brock Lesnar and Shane Carwin, and Cormier, a former Olympic-level wrestler, certainly fits that mold.
