Franks, who spent the last eight seasons with Green Bay, will likely be the backup to Chris Baker. The 30-year-old Franks has battled injuries and his offensive production has slipped the last few years after Pro Bowl seasons from 2001-03. He was relegated to backup duty behind Donald Lee last season.
The No. 14 overall pick out of Miami in the 2000 draft had a career-low 18 catches for 132 yards and three touchdowns in eight games last season, but is still regarded as a strong blocker. He has 256 receptions for 2,300 yards and 32 TDs in his career.
