9:04 AM PT -- TMZ Sports has obtained the police report which says officers responded to the call of a male driver passed out behind the wheel of a black Rolls-Royce SUV.
Cops say when they responded to the scene, they found the SUV -- with the engine running -- in the middle of traffic ... with Broner "unconscious, but breathing" in the driver's seat.
Cops say they tried to bang on the window to wake Broner up -- but ultimately needed to shake the car to get a response from Adrien.
Once he woke up, a confused Broner rolled down his window, and a cop reached inside the car and put it in park.
