Khabib Nurmagomedov says he's down to fight Floyd Mayweather ... but The Eagle is floating the idea of a mixed boxing/MMA match!!
"Like maybe 11 rounds boxing, 1 round MMA," Khabib tells TMZ Sports.
Of course, Khabib and Floyd have flirted heavily with the idea of a fight for years ... with Nurmagomedov's manager, Ali Abdelaziz, telling us TBE has been "begging" for a scrap.
In fact, Ali says they even got a $100 MILLION offer from some powerful Saudis to put on the fight in the Middle East!
