The Tampa Bay Buccaneers signed free-agent quarterback Jeff Garcia on Saturday and obtained the rights to Jake Plummer from Denver, adding two quarterbacks to compete with Chris Simms next season. Plummer, who reportedly was thinking of retiring if he was traded, was sent to the Buccaneers for a conditional 2008 draft choice, the Broncos said. The 37-year-old Garcia, who last year led Philadelphia to the playoffs filling in for the injured Donovan McNabb, agreed to terms a day after talking with the Oakland Raiders. The signing was reported on the Bucs' web site.
