Cardinals LT Nate Potter (ankle) is listed as questionable for Sunday's regular season finale against the 49ers. It's the same injury Potter played through last week when he allowed three sacks to Julius Peppers. If the Cardinals are forced to start D'Anthony Batiste at left tackle, it would give Aldon Smith the best possible matchup he could have to overtake J.J. Watt for the NFL sack lead and put him in position to break Michael Strahan's all-time record. Potter hasn't missed a game since being promoted to the starting lineup in Week 11 and is capable of playing on limited practice.
