The UFC has released the full video of Countdown To UFC 144 to promote Saturday's UFC 144: Edgar vs. Henderson event, taking place in Japan. While seven fights are making the main pay-per-view broadcast, they focused on four specific bouts: Frankie Edgar vs. Ben Henderson, Quinton Jackson vs. Ryan Bader, Yoshihiro Akiyama vs. Jake Shields, and Anthony Pettis vs. Joe Lauzon.

Here's how the UFC describes each of the four bouts:

Frankie Edgar vs. Ben Henderson: "The most unlikely UFC champion meets the former WEC champion in a battle between two true athletes. Watch lightweight champion Frankie Edgar fight Benson Henderson live on Saturday, February 25."

Quinton Jackson vs. Ryan Bader: "Former light heavyweight champion Rampage Jackson relishes the chance to return to Japan and his PRIDE-era fans, but Ryan Bader isn't intimidated by fighting a legend... he's done it before."

Yoshihiro Akiyama vs. Jake Shields: "Japanese superstar Sexyama drops down to welterweight as Jake Shields plans another run up the ranks of the 170-pound division."

Anthony Pettis vs. Joe Lauzon: "Two lightweights with flashy finishes to their names will face one another - hear what bonus-hunter Joe Lauzon and human highlight reel Anthony Pettis are doing to prepare for what could be the most exciting fight of the year."
