It seems everyone's accepted Khabib Nurmagomedov is retired for good ... the MMA legend's manager says the UFC didn't even reach out about a possible return to the Octagon as Dana White's promotion put together one of their biggest events ever!
UFC 300 is going down Saturday, April 13 in Las Vegas ... and it's a landmark event (UFC 1 was in 1993!). The card's stacked -- from the early prelims through the main event, Alex Pereira vs. Jamahal Hill -- with 13 strong fights!
