Buccaneers add veteran QB Leftwich
Leftwich's deal is for $7.5 million, a source told ESPN.com's John Clayton.
Leftwich, 29, a first-round draft pick by the Jacksonville Jaguars out of Marshall in 2003, won a Super Bowl ring last season as a backup with the Steelers.
The 6-foot-5, 250-pounder has started just eight games since 2006, his last season with the Jaguars. He played for the Atlanta Falcons in 2007.
Leftwich passed for 303 yards with two touchdowns in five appearances with the Steelers last season as Ben Roethlisberger's backup.
