Dustin Poirier has agreed to challenge Charles Oliveira for the UFC lightweight title in December.

After lengthy talks, Poirier, who has a 28-6 record, confirmed on Sunday that he will go up against Oliveira, tweeting "Signed, Sealed, Delivered."

ESPN subsequently reported the 32-year-old's representatives had confirmed the bout will take place at UFC 269 on December 11, as Poirier looks to continue an impressive 2021.

He has twice beaten Conor McGregor this year, first in January at UFC 257 and then again at UFC 264 six months later.

Poirier, a former interim champion, previously challenged former lightweight champion Khabib Nurmagomedov in 2019, though lost via submission.

Oliveira, a year Poirier's junior, will be a similarly stern test. The Brazilian took the title in May after defeating Michael Chandler and is on a nine-fight winning run.
