Dustin Poirier and Dan Hooker are expected to headline the UFC's Fight Night in San Diego on May 16, according to MMAJunkie's Mike Bohn.
Bohn's two sources requested anonymity because contracts have not been signed and an official announcement has not been made.
Poirier, known as "The Diamond," has not stepped into the octagon since losing by third-round submission to Khabib Nurmagomedov in UFC 242 on Sept. 7, 2019. The 31-year-old is 25-5-0 in his career.
Hooker most recently headlined UFC's Fight Night in New Zealand on Feb. 22, where he won a split decision in five rounds of Paul Felder.
