Conor McGregor says he "accepts" a fight with UFC rising star Khamzat Chimaev ... but calm down everyone, it's far from official.
Here's the deal ... Khamzat -- who's dominated in his first 2 fights in the UFC -- called out Conor, Nate Diaz and Jorge Masvidal on social media Thursday.
"I’m getting bored, please @danawhite give me @NateDiaz209 @GamebredFighter @TheNotoriousMMA same night," Khamzat tweeted.
"I can smash all these guys ... I’m not cocky guy I’m just confident. I understand if they don’t want to fight me."
