Showing great sportsmanship, after their UFC 242 bout where Khabib submitted Poirier in the third round, the two exchanged their fight worn shirts.

The shirts were made by Reebok. Poirier's shirt had "Lafayette, Louisiana" printed on it, along with Poirier's name. Khabib was never shy about his plans to auction the shirt off, as with over 17 million Facebook fans, he figured he could get a significant amount for it. He was right. And all of that money went to Dustin Poirier's charity The Good Fight Foundation.

Poirier told MMA Junkie that the shirt sold for $100,000.

“It’s great because it’s going to help a lot of people,” Poirier told MMA Junkie. “I’m proud of that. I appreciate them helping out the charity. It’s been growing and I’m very grateful for that.”

As if that wasn't awesome enough, Poirier tweeted this out yesterday.

The initial goal to help in building water wells to repair a ruined water supply at an orphanage and school in Uganda was $25,000. With donates received online, the goal was surpassed with up to $33,000 given. Now, with these two extremely generous donations, the foundation will be able to help so much more.

Good on both of these guys!
