Raiders set to sign QB after O’Connell’s thumb injury

The Raiders appear set to add help from outside their building after quarterback Aidan O’Connell fractured his right thumb in Sunday’s 20-15 loss to the Rams.

The team is expected to sign quarterback Desmond Ridder off the Cardinals’ practice squad, according to sources with knowledge of the situation.

Ridder, a third-round pick in 2022, started 13 games for the Falcons last year. He completed 64.2 percent of his passes for 2,836 yards, 12 touchdowns and 12 interceptions.

The only other quarterbacks in the Raiders’ organization besides O’Connell are veteran Gardner Minshew and undrafted rookie Carter Bradley, who is on the team’s practice squad.

Minshew leads the NFL with 10 turnovers this season.
