UFC 299: Dustin Poirier vs. Benoit Saint Denis: Live round-by-round updates 

The co-main event at UFC 299 features an electrifying lightweight contest between former interim champion Dustin Poirier and the dangerous up-and-comer Benoit Saint Denis.

Poirier's career has definitely seen better days. He is 3-2 in his last five and most recently suffered a second-round KO against Justin Gaethje in their UFC 291 BMF title fight.

'The Diamond' is in dire need of a win at the pay-per-view since a loss against the No.12 ranked fighter will essentially negate his chances for a title shot in the foreseeable future. At the same time, a statement win against the up-and-comer might even thrust him back into title contention.

The Louisiana native holds a record of 29-8 with one no-contest (NC) and boasts wins against a veritable list of MMA greats, including Conor McGregor, Max Holloway, and Gaethje, among others.

In the other half of the co-main, 'God of War' has a unique opportunity this Saturday. A win against Poirier will most certainly catapult him to the top-5 of the division and greatly improve his chances for an eventual title shot. Saint Denis is 13-1 with one NC in MMA and is currently on a five-fight win streak.

According to the UFC's official website, the Frenchman is a -170 favorite over 'The Diamond' (+142 underdog) for the match-up.

As the pair separates, the Frenchman unloads a quick 1-2 on his opponents. Poirier tries another guillotine, this time standing up. Both fighters engage readily, landing their share of shots.

Saint Denis tries to look in a kimura. Poirier survives—more back-and-forth action by both men. 'The Diamon' tries a third guillotine; but Saint Denis gets out of danger again.

The 28-year-old secures his opponent's back after a scramble threatening a rear naked choke. The Frenchman transitions to an arm bar but is unable to finish the submission as the round comes to a close.

Poirier connects with an uppercut. He then unloads a left hand, which wobbles his foe. He briefly tries to go back to another Guillotine but is quickly forced into another stand-up scramble.
