Steelers coach Mike Tomlin is looking to fortify the team's offensive line. Three of the team's starters on the line were helped off the field during Sunday night's win over the Colts. Tomlin said the Steelers are "open to looking to maybe bring someone in" this week. He stressed the team is looking for depth, not someone to show up on Wednesday and be ready to play in Sunday's game at Houston. "It would just be for practice purposes only," Tomlin said.
