Dustin Poirier shares graphic update on staph infection as his foot seemingly continues to swell

Former UFC interim lightweight champ Dustin Poirier recently gave an update on his staph infection.

The 33-year-old American fighter last fought Michael Chandler in a lightweight matchup at UFC 281. The duo put on electrifying performances going back and forth for three rounds. 'The Diamond' was ultimately successful in defeating 'Iron' via a rear-naked choke at the 2:00 mark in the third round. The match also earned the 'Fight of the Night' award at the event.

Popular MMA journalist Brett Okamoto reported that 'The Diamond' is suffering from a staph infection in his foot. Reports suggested that his condition was worsening and had not been responding to antibiotics.

Okamoto tweeted:

"Some context on Dustin Poirier’s (@DustinPoirier) IG posts about being hospitalized … told me it’s staph, but he’s not responding to antibiotics over the last 24 hours. Undergoing further blood work now, hopefully get some answers today."

In a recent update, Dustin Poirier shared a picture of his foot which looked tremendously swollen, thus indicating no signs of recovery. Posting the image, 'The Diamond' wrote:

"Wut d a helllll"

Poirier is currently on a one-fight winning streak in the promotion, and holds a pro record of 29 wins and 7 losses in MMA. His current staph infection might prove to be a major setback towards a title shot in the UFC.

Conor McGregor has once again got into a Twitter brawl with Dustin Poirier after news of 'The Diamond' getting hospitalized broke.

Poirer, too, didn't sit silently as he fired back at 'The Notorious' over his acting debut and recent allegations of PED use:

"You done filming Roid House and ready to get slapped around again!?"

This was not the end of their feud, as the two fighters went one step further, with McGregor challenging Poirier to a fourth fight:

"Ye I'm in Amderdam jacked like [Jean-Claude] van damn. You weren't just hurt pal. You were scared hurt don't forget it. I'm coming back to put you in a box. Full of it. I'm sending you off this earth. Permanent. Stay waiting for the road house as well pal you and the missus will love it."

Given the animosity between the two fighters and the fact that their most recent fight ended in a doctor's stoppage due to the Irishman's leg injury, a McGregor vs. Poirier 4 cannot be ruled out at this time. McGregor has since stated that he will be back in the USADA testing pool in February.
