Porter (back) is officially listed as out for Sunday's game against the Patriots, Brooke Pryor of ESPN.com reports.
Porter missed all of training camp and was sidelined in Week 1 due to what the Steelers are saying is a back injury, and that's what is officially keeping him out Sunday as well. With that said, he has expressed dissatisfaction about an inability to get a contract extension in place in recent weeks. Asante Samuel should continue to see an uptick in reps against New England.
