Colon, 29, is set to earn $5.5 million next season as part of the five-year, $29 million contract he signed in 2011. The sense around the Steelers was that Colon would be cut as Pittsburgh sought to overhaul its offensive front with more athletic and durable linemen. Colon has started only 13 games over the past two years and wound up on injured reserve for the third straight season in 2012.
