Moments after Blueface got stabbed in a boxing gym, his trainer dialed 911 and the call got pretty intense ... with the operator trying to get details of the attack, as the trainer tried to get medics to save Blue.
TMZ Hip Hop obtained audio of the 911 call that launched paramedics to the bloody scene on August 23 at the Kaminsky Boxing Gym in L.A.'s San Fernando Valley.
On the call, the trainer -- who also owns the gym -- tells the operator a random guy came in and "stabbed my client" .
