Cedric Ceballos says he's now COVID-free ... but there's bad news, he's still far from 100 percent -- explaining Monday he's still in the ICU with serious breathing issues.
Ceballos -- the 1992 NBA Dunk Contest champ -- posted a photo of himself in the ICU last Tuesday ... saying COVID-19 was "officially kicking my butt."
The 52-year-old asked for fans to pray for his recovery ... and on Monday, he announced he's now testing negative for COVID.
But Ceballos clearly ain't out of the woods yet, 'cause he said the effects of the virus are still wreaking havoc on his body.
