Dustin Poirier's wife shares horrifying clip of 'The Diamond's ballooned up foot infected with staph

Dustin Poirier spent his second day in the hospital as the No.2-ranked lightweight contender battles a staph infection. His wife, Jolie Poirier, recently shared an update on his condition.

Sharing a video to her Instagram story, Jolie displayed a glimpse of the Louisiana native's swollen left foot as a result of the infection. She wrote:

"Not making much progress! Actually looking worse."

Brett Okamoto of ESPN MMA first reported the lightweight's ailment on Twitter after Poirier posted some stories on Instagram about being hospitalized. 'The Diamond' stated:

"Going on day 2 in the hospital. S**t's getting serious."

Okamoto confirmed that it was indeed a staph infection that plagued the former interim champion. It was also reported that Poirier was not responding to the medication administered and will remain in hospital until further developments.

Dustin Poirier last fought Michael Chandler at UFC 281 in what could only be described as a war. 'The Diamond' emerged victorious with a submission in the third round.

Anthony Smith explains why Dustin Poirier would jump at the chance to fight Conor McGregor

Anthony Smith recently claimed that Dustin Poirier will take any opportunity to fight Conor McGregor for the fourth time, insisting that his displayed lack of interest in making that happen is simply an act.

Speaking to Michael Bisping on the Believe You Me podcast, Smith claimed that Poirier would not refuse the money-making opportunity afforded by the UFC's poster boy. He stated:

"We all know the prize tag that comes with a Conor McGregor fight... So you can say all you want, 'Oh! I don't want it.' I love Dustin Poirier, I love everything he stands for... Dustin's full of s**t. He's going to take that paycheck any chance he gets. I'm here to watch it, I'll buy it and I'll put money in his pocket. I'm here for it. Just for the buildup."

Watch the full podcast episode below:

Dustin Poirier has beaten the former two-division champion twice in the past. They have faced each other three times in total and Poirier boasts a record of 2-1 over the Irishman. Their last fight saw McGregor suffer a leg fracture that's forced him to remain on the sidelines for more than a year.

However, considering the recent Twitter barbs that the two rivals exchanged, it is possible that we will see a fourth fight between the two.
