Gannon, who was the Oakland Raiders most pivotal free agent signing in recent years, is expected to be joined by owner Al Davis. The last two seasons have ended on injured reserve. Gannon suffered a cracked vertebra in his neck last season.
Gannon, who signed with the Raiders as a free agent in 1999, led the team to three consecutive AFC Western Division titles from 2000-02 and compiled a 45-29 regular season record as a starter from 1999-2004. He started in 71 consecutive regular season games from 1999-2003, a Raiders record for quarterbacks.
Gannon led the Raiders to the AFC Championship Game following the 2000 and 2002 seasons. He guided the Raiders to Super Bowl XXXVII, as the Raiders became the only team in NFL history to play in Super Bowls in five different decades.
