Miami Heat guard Gerald Green was unconscious and bleeding when someone at his condo complex called 911 ... TMZ Sports has learned.
We obtained the call ... made Wednesday morning ... in which the caller tells 911, "I have a resident that just passed out. He’s bleeding. He just passed out right now."
The operator informs the caller that help is on the way -- and gives instructions on how to treat Green until emergency personnel arrives.
The nature of Green's illness is still unclear -- but as we previously reported, multiple people at the complex tell us they saw him acting strange in the lobby and screaming from the top of his lungs.
Once Miami-Dade Fire and Rescue arrived to the scene, they requested assistance because of a “combative patient” ... so says the Miami Herald.
Eventually, Green was put in an ambulance and taken to a nearby hospital. No word on his current condition.
