Dustin Poirier is already considering a return to combat sports, but in the boxing ring.

Poirier has expressed strong interest in facing long-time rival Nate Diaz on a Zuffa Boxing card. Poirier’s MMA career seemingly concluded in his hometown of New Orleans in July, following a unanimous decision loss to Max Holloway in their BMF trilogy fight at UFC 318. Despite the retirement, the opportunity to finally settle his feud with Diaz appears to be too tempting.

The rivalry between the two dates back to a scheduled fight at UFC 230, which Poirier claims Diaz “negotiated himself out” of. Diaz has already proving his commercial viability in the boxing world with a majority decision win against Jorge Masvidal last July. A boxing match under the Zuffa banner would allow Poirier to test his hands in a new sport.
