New UFC 173 full poster pic for 'Barao vs Dillashaw' Memorial Day Weekend pay-per-view (PPV) on May 24 in Las Vegas

Ultimate Fighting Championship (UFC) has released the new poster for UFC 173: "Barao vs. Dillashaw," which headlines the promotion's annual Memorial Day Weekend card, which will take place at MGM Grand Garden Arena in Las Vegas, Nevada, on May 24, 2014.

Take a look:

Compare it to the last UFC 173 poster right here.

Barao is fresh off a first-round technical knockout of Urijah Faber at UFC 169 back in Feb. 2014, which served as his first-ever undisputed 135-pound title defense because former champion Dominick Cruz cannot stay healthy. The Brazilian is in the midst of a ridiculous 32-fight mixed martial arts (MMA) win streak.

Dillashaw, the No. 5-ranked fighter in the division, picked up an important unanimous decision win over Mike Easton at UFC Fight Night 35 earlier this year. The Team Alpha Male-trained standout has just one loss, Raphael Assuncao, in six appearances inside the Octagon since losing out to John Dodson for The Ultimate Fighter (TUF) 14 crown back in 2011.

Assuncao is the leading candidate to challenge the winner after he heals up from injury.

In addition to the new main event, UFC 173 will feature the return of former heavyweight champion, Junior dos Santos, against Stipe Miocic, as well as a pair of lightweight matches that feature Anthony Ferguson vs. Katsunori Kikuno and James Krause vs. Jamie Varner.
