PITTSBURGH – (WPXI) – Police have arrested two people, including free agent NFL WR and QB Terrelle Pryor, after Pryor was stabbed in Pittsburgh. Pryor, 30, reportedly underwent surgery after a violent dispute inside his Heinz Lofts apartment. A woman — identified as Shalaya Briston, 24 — was also injured. According to the police criminal complaint, officers were initially called to the Heinz Lofts apartments around 4:15 a.m. Saturday for a domestic disturbance call. When police arrived, they found a trail of blood leading from Pryor’s apartment to the elevator and across the garage to his Mercedes Benz. Inside Pryor’s car, police said detectives found a semi-automatic Glock pistol with a flashlight on the front passenger seat. Detectives later found out Pryor and Briston were involved in a relationship, and that they lived in the Heinz Lofts apartment together. Witnesses described their relationship as very volatile, and witnesses told police that Pryor “always had his hands all over her.” According to the criminal complaint, another witness told police the incident started when Briston and Pryor got into an argument in the hallway outside their apartment. It escalated, and once inside, police said Pryor knocked that witness to the floor. Pryor then allegedly grabbed Briston and “began to tussle with her.” Police said it continued into the kitchen, and as witnesses were trying to break it up, Pryor backed away and grabbed his chest. He then ran out of the apartment while bleeding noticeably, according to police. Pryor was a standout with the football team while playing in high school at Jeannette.
