TMZ Sports has obtained the dramatic 911 call made after Glen Rice Jr. was shot Sunday -- in which the caller says he personally witnessed Rice try to ditch a handgun while "leaking" blood.
The caller is VERY descriptive -- saying he definitely heard gunfire and then saw the ex-NBA player frantically try to flag down a friend while screaming, "They just shot me."
As we previously reported, Rice was shot outside T.I.'s restaurant in Atlanta -- and according to the caller, he was "soaked" in blood which was spewing from his upper left thigh.
At one point, the caller becomes afraid for his own safety -- and finally decides to leave the scene.
A short time later, cops pulled over the Porsche that picked up Rice -- and he was arrested for weed possession and reckless conduct.
