Dustin Poirier details mental health struggle after loss to Justin Gaethje

Dustin Poirier is as battle-hardened as they come, but his recent comments prove that looks can be deceptive.

During his recent appearance on Ariel Helwani's The MMA Hour, 'The Diamond' revealed that he struggled with his mental health after his loss to Justin Gaethje at UFC 291 where he got knocked out in the second round.

He said:

"After the Gaethje fight ... I went through some real mental struggles, man. I was going through some stuff. [It got] really bad, really bad ... It is very scary."

He added that it got to the point where he got worried for his well-being. However, watching Alexander Volkanovski being open and vulnerable about his emotions helped him realize that he was not alone in this feeling.

"Whenever I saw Volk talking and kind of expressing himself and being honest ... we're going through the same thing. I actually started doing therapy after the fight. I think its important to open up and talk about how you feel."

Cedric Doumbe blames Marc Goddard for the PFL loss

Cedric Doumbe opened up about his recent loss at PFL France on The MMA Hour.

On March 7, Doumbe returned to the smart cage after his debut win over Jordan Zebo to face undefeated prospect Baissangour Chamsoudinov. Doumbe suffered a loss for the first time, but not because he was outclassed by his opponent.

In the third round, a splinter that got stuck in his toe triggered confusion, which led to Marc Goddard stopping the fight resulting in a bizarre stoppage.

The Cameroonian-born French told Helwani how he was uncomfortable about the splinter but was unable to convey the same to the referee due to the language barrier.

He said:

"If you see the footage, I tried to remove it by myself with the other foot. Didn't work, so then I raised my hand and talked to the referee. I said I have something under my foot as I didn't know how to say splinter. He said 'Don't stop. Keep going. Fight.' I was like 'Okay, he doesn't want to understand.'"

He added that his opponent was fine with him taking it out, and he was the one who paused to talk to the referee the second time.
