Nathan Peterman will be the only other quarterback in the Raiders’ roster.

Glennon, 2-9, was discharged by the Arizona Cardinals on March 8 after just one season with this team. He appeared in two games with Arizona, completing 15 of 21 passes for 174 yards and a touchdown.

The Chicago Bears signed Glennon in 2017 to be their newcomer, but later traded to the No. 2 overall pick in the draft to choose quarterback Mitchell Trubisky. Glennon opened the 2017 season as the newcomer but struggled in four games before being benched in favour of Trubisky. Chicago published Glennon after this season.

He began his career with the Tampa Bay Buccaneers after being selected in the next round (73rd overall) of this 2013 draft.

Back in 27 games (22 starts), he’s completed 60.9 percent of his pass attempts for 5,107 yards, 35 touchdowns and 20 interceptions.

The Raiders on Friday additionally signed free-agent basic security Curtis Riley, who had four interceptions while starting all 16 games for the New York Giants last season.

Riley also put career-highs together with 73 tackles and five passes defensed. He played with his first three seasons with the Tennessee Titans.
