The Pittsburgh Steelers have placed offensive tackle Willie Colon on IR, ending his season. Meanwhile, the team has signed OL Jamon Meredith (6-5, 305). Meredith who was the Packers 5th round pick in 2009, has bounced around the league, spending time with the Bills, Lions and the New York Giants, recently. He started 4 games for the Bills in 2009. Meredith can play both guard and tackle but is said to lack the athleticism to adequetely play guard.
