The Pittsburgh Steelers have announced that center/guard Sean Mahan has been trade to the Buccaneers for an undisclosed 2009 draft pick.

Coincidentally, the Steelers signed Mahan from the Bucs in 2007, and he started every game in Pittsburgh a year ago.

But Mahan recently lost the starting center job to Justin Hartwig, and the Steelers apparently didn’t want to carry Mahan’s $2.175 million salary.

Mahan is signed for four more seasons.  He is due to earn salaries of $3.175 million in 2009, $3.5 million in 2010, and $3.5 million in 2011.

Mahan was a fifth-round pick of the Bucs in 2003.
