Dustin Poirier says his fight against Benoit Saint-Denis "is on" after a "misunderstanding" on his part. Earlier on Thursday, Poirier posted on X, formerly known as Twitter, that the fight was "off."

The Diamond @DustinPoirier

Sorry folks, I jumped the gun, I couldn't get a hold of my manager for a few days. I just spoke with him and Hunter. Misunderstanding on my part. Fight is on! See you March 9th Miami!!! <a href="">

Shortly after saying the fight was off, Poirier spoke to MMA journalist Ariel Helwani to explain his post:

Ariel Helwani @arielhelwani

I reached out to <a href="">@DustinPoirier</a> about his tweet that the BSD fight at 299 is off.<br><br>His response: <br><br>"There was no contractual agreement before the fight was announced and we couldn't come to terms."

Poirier is coming off a loss to Justin Gaethje at UFC 291, which cost him the "BMF" championship. He's lost two of his last three fights overall.

Saint-Denis is one of the fastest-rising fighters in mixed martial arts.

After losing his UFC debut against Elizeu Zaleski dos Santos at UFC 267, Saint-Denis has reeled off five straight victories. He earned Performance of the Night honors for his knockout of Matt Frevola at UFC 295 in November.

The bout against Poirier will be by far the highest-profile matchup of Saint-Denis' career.

UFC 299 is slated for March 9 at the Kaseya Center in Miami, Florida.
