The Steelers re-signed long snapper and linebacker Matt Stewart on Monday and released wide receiver Isaiah Williams to make room for him. It is a bit of a curious move unless current long snapper Greg Warren is having problems with his knees again. This is Stewart\'s second time on the roster this offseason as he was signed back in June and released right before training camp started. Another theory behind the move is that free safety Ryan Clark is likely to sit out the next preseason game versus Denver as a precaution and cornerback Keenan Lewis could be out as well after suffering a concussion Saturday in New York. Stewart would be another body that could lend a hand on special teams if needed. There could be some more bumps and bruises we do not know about yet as well. Unless there is worry with Warren health wise, I find it hard to believe Stewart is coming in to take over long snapping duties this late in preseason, but it is not out of the question either. Williams had zero chance of making the roster and only had a brief appearance in the second preseason game against the Giants.
