A woman was charged with attempted homicide Saturday after allegedly stabbing and seriously injuring former Ohio State quarterback and NFL free agent wide receiver Terrelle Pryor, who was also charged in the incident.

Shalaya Briston, whom witnesses said was in a relationship with Pryor, was arrested on suspicion of attempted homicide and aggravated assault after she allegedly stabbed Pryor in their Pittsburgh apartment early Saturday morning, according to police.

Pryor, who was hospitalized as a result of the incident, was charged with simple assault.

According to copies of criminal complaints obtained by USA TODAY Sports, witnesses told police that Briston, 24, and Pryor lived together and had co-signed the lease on the apartment in which the altercation occurred. Witnesses also indicated that the couple had previously had "domestic issues."

In a news release announcing the charges, police described Briston and Pryor as "mutual combatants in this incident."

According to the criminal complaints, two unnamed witnesses told police that they went out to dinner with Briston and Pryor on Friday night before returning to the couple's apartment at the Heinz Lofts in Pittsburgh, just north of the Allegheny River. The witnesses told police that the couple got into an argument early Saturday morning that turned physical.

While one witness said they did not recall what happened next, the other witness said Pryor grabbed Briston and tussled with her from the hallway into the kitchen. According to that witness, Pryor then pulled away and grabbed his chest before exiting the apartment.

Police allege that Briston stabbed Pryor during this altercation, though Briston also allegedly sustained injuries, including a bruise on her nose.

According to the criminal complaints, Briston and the two unnamed witnesses then drove Pryor to UPMC Mercy Hospital, where he was found in critical condition shortly after 4:30 a.m. local time and taken into surgery.

One officer reported in Briston's criminal complaint that, while at the hospital, one of the witnesses said "the only reason I'm here was to make sure that he didn't die" and "we should have just let him die." A second officer overheard the same witness saying "something to the effect of 'she was just defending herself and had to do it.'"

Briston agreed to speak with police about the incident but then said she didn't see anything or know anything and declined to elaborate, according to her criminal complaint.

While the severity of Pryor's injuries were immediately unclear, an officer described Pryor on police dispatch audio as having been stabbed in the upper part of his chest. Two residents in the building, who initially called police early Saturday morning to report a domestic disturbance, told responding officers that they saw "a large amount of blood" in the building's elevator.

Gregory Diulus, one of Pryor's agents, told The Associated Press that the 30-year-old's family was with him at the hospital and that Pryor was expected to make a full recovery. Diulus did not immediately respond to messages left by USA TODAY Sports seeking an update on Pryor's health.

WTAE-TV first reported that Pryor had been stabbed Saturday morning.

A Pennsylvania native who went on to star at Ohio State, Pryor moved from quarterback to wide receiver at the professional level and has played with nine different teams over the course of his NFL career. He most recently signed a one-year contract with the Jacksonville Jaguars earlier this year before being placed on injured reserve in early September and released shortly thereafter.
