Terrelle Pryor was stabbed with a kitchen knife, lost 3.5 liters of blood and was within "minutes" of dying after the scuffle with his GF ... this according to the NFL player's attorney.
In a press conference with media members Wednesday, Stephen Colafella described the state Pryor was in after a fight in his apartment with Shalaya Briston on Nov. 30 -- and he says the scene was grim.
Colafella told reporters Pryor had a "very deep" stab wound above his left pec that just missed a major artery .
