Josh Johnson’s reunion with Jon Gruden didn’t last long.

The Raiders announced Thursday that they have released Johnson, a veteran quarterback the team signed to a one-year deal in March.

Johnson was the last quarterback Gruden drafted during his coaching stint with the Tampa Bay Buccaneers in 2008.

The Raiders’ quarterback depth charts now stands at three with starter Derek Carr and backups EJ Manuel and Connor Cook.

Johnson, the cousin of Raiders running back Marshawn Lynch, has played in 29 games and started five during his 10-year career. The fifth-round pick out of the University of San Diego has been with 11 NFL teams.
