Calvin Anderson: Everything you need to know

The Steelers released Anderson (shoulder) on Tuesday, Aaron Wilson of KPRC 2 Houston reports. Anderson spent the past two seasons in Pittsburgh, appearing in 13 regular-season games without making any starts. The 29-year-old has seemingly recovered from the shoulder injury that landed him on the team's injured reserve last December.

Anderson (knee) was placed on the reserve/injured list Wednesday, Teresa Varley of the Steelers' official site reports. Anderson has appeared in nine games for the Steelers this season, but he suffered a knee injury in Week 13 that could cost him the rest of his season. He won't be eligible to be activated until the postseason, if Pittsburgh qualifies.

Anderson (knee) has been ruled out ahead of Monday night's game against the Dolphins, Teresa Varley of the Steelers' official site reports. Anderson has been available for just one game this season and will miss yet another contest in Week 15. As the lead depth option behind starting tackles Andrus Peat and Troy Fautanu, the 29-year-old cannot stay on the field as he battles a persistent knee injury. This absence may be more significant, as Peat (concussion) is also questionable for Monday's game.
