Pryor, 26 next month, last appeared in a NFL game with the Oakland Raiders in 2013. The Raiders selected Pryor in the 2011 supplemental draft, and over his three seasons with the team, Pryor appeared in 15 games and completed 56.3% of his passes for 1,953 yards, nine touchdowns and 12 interceptions.
"I'm still young for a quarterback," Pryor said after signing with the Bengals, according to the team's website. "All you can do is learn. Hopefully I showed the coaches I can not only be a leader, but I have the foundation to get better."
The former Ohio State quarterback was traded to the Seattle Seahawks in April 2014, but was cut during final roster cuts that August. After numerous tryouts with teams throughout the 2014 season, Pryor signed with the Kansas City Chiefs this January but was released last week.
Pryor is expected to compete for the Bengals' third quarterback spot with Josh Johnson behind starter Andy Dalton and backup A.J. McCarron. Offensive coordinator Hue Jackson was also in Oakland with Pryor, serving as offensive coordinator in 2010 and head coach in 2011.
"That's a different quarterback,” Jackson said. "The guy I had was coming right out Ohio State and whatever that was and didn't have the first six weeks and I didn't have an opportunity to have a word with him. I had him for one day in training camp and then we got him, the season had already started, so this guy's improved. He's a very talented young man. But again, we'll see where we are."
