The Steelers have announced that they have signed former Steelers LB Stevenson Sylvester. LB Kion Wilson has been released. I reported earlier that the team had Sylvester in for a workout yesterday. Sylvester has been a free agent since being cut by the team on August 25th. Coach Tomlin said that Kion Wilson was a partial participant in practice yesterday. He injured his hamstring during the loss to the Vikings. Tomlin also mentioned that Da’Mon Cromartie-Smith was questionable with an injured hip flexor, so Sylvester’s services may likely be needed mainly to help on special teams.
