MMA fighter Dada 5000 is doing MUCH better after a frightening health scare following his fight with Kimbo Slice at Bellator 149 this past weekend ... so says Dada's rep.
We spoke with Mike Vazquez -- who says he was with Dada in the hospital following the fight -- and he tells us, "Dada is recovering well. On his feet and moving around. Back to his usual self."
"He should be out [of the hospital] by the end of the week and can personally address [then]."
Dada's family had issued a statement following the fight -- explaining that he had "accumulated extremely high levels of potassium in his blood which led to severe dehydration, fatigue and renal failure."
