The Pittsburgh Steelers traded two offensive linemen away during their final roster cuts this year. They are slated to face both of them later on in the season, or at least their teams. This week, they are very likely to see former C Kendrick Green lining up at guard for the Houston Texans after moving him for a future sixth-round pick.
In fact, he has already been forced into the lineup in recent weeks due to injuries, playing the past two games. They have numerous linemen on the Reserve/Injured List already and multiple injuries to the starting lineup they are currently dealing with, so it would take a minor miracle for him not to play against his former team this weekend.
