Free-agent receiver Terrelle Pryor is in critical condition following surgery after he was stabbed Friday night at his apartment, a source told ESPN’s Adam Schefter.

Allegheny District Attorney spokesman Mike Manko confirmed Pryor was the victim of a stabbing.

Pryor was stabbed in the chest and shoulder, according to the source.

The incident took place at the Heinz Lofts apartment complex in Pittsburgh, according to WTAE-TV.

An unidentified woman is in police custody, according to the station.

Pittsburgh Police said they are investigating after officers were called for a male stabbing victim who had walked into the hospital just after 4:30 a.m. ET. While police did not identify the man, a source confirmed to ESPN’s Jeremy Fowler that this was Pryor.

Pryor, 30, entered the league in 2011 and has played with the Oakland Raiders, Cleveland Browns, Washington Redskins, Buffalo Bills and New York Jets.

He hasn’t played this season after he was released by the Jacksonville Jaguars in September.
