Dustin Poirier is not a sore loser.
Poirier offered Charles Oliveira a $20,000 donation to the charity of his choice after being submitted by the UFC lightweight champion at Saturday's UFC 269 pay-per-view.
"I saw a video this week of him showing where he grew up and where his mom cooked dinner for him. I think it was an old video and saw some of the sights of where he grew up and just how little they had," Poirier told reporters after the fight (24:17 mark). "It came to me this week, I thought I was going to let him know—win, lose or draw—that me and the Good Fight Foundation would donate $20,000 to his city in Brazil and put the money wherever they think it needs to be.
