ESPN's Adam Schefter had reported the wideout was previously in critical condition post-surgery.
Pryor reportedly underwent surgery to treat stab wounds to the shoulder and chest, and an unidentified woman is in police custody.
Per ESPN's Jeremy Fowler, a family friend said they expect Pryor to survive. Josina Anderson of ESPN also spoke to a family spokesman, who said detectives have visited the hospital where Pryor is being treated after the stabbing.
The 30-year-old Pryor began his NFL career as a quarterback with the Oakland Raiders in 2011 after a standout collegiate career at quarterback with Ohio State.
Pryor went just 3-7 as a starter and threw nine touchdowns to 12 interceptions, however, which led to the Cleveland Browns converting him to wide receiver. That move paid dividends in 2016, as Pryor set career highs with 77 receptions for 1,007 yards and four touchdowns.
After reaching that high-water mark, Pryor dropped off significantly. He signed a one-year deal with the Washington Redskins in free agency and finished with just 20 receptions for 240 yards and one touchdown.
Pryor then split last season between the New York Jets and Buffalo Bills, registering 16 catches for 252 yards and two scores.
He spent the 2019 preseason with the Jacksonville Jaguars but was placed on injured reserve in August and then released from the team.
The Jeannette, Pennsylvania, native has gone unsigned since then.
