Griffin was signed to the Buccaneers' practice squad Wednesday, Greg Auman of The Athletic reports.
Griffin will return to the Buccaneers' for an eighth consecutive season, making him the longest tenured quarterback in franchise history. That being said, the 32-year-old has not appeared in a game since 2020 and has thrown four total regular-season passes since entering the league in 2013. Griffin will most likely spend the entire season on the practice squad barring any injuries.
