"My mindset is I'm going to play again."
That's Florida Gators star Keyontae Johnson opening up about his battle to get back on the basketball court just 2 months after he collapsed during a game ... despite still not knowing exactly what caused his medical emergency.
It was on Dec. 12 when the 21-year-old star crashed to the hardwood during a game against Florida State. As fate would have it, there was a cardiologist sitting in the stands that day who raced over to Johnson to provide medical aid.
"I was passed out. I could have died," Johnson told FloridaGators.
