Wall is doubtful for Sunday's game against the Rockets due to abdominal soreness, Tomer Azarly of ClutchPoints.com reports.
Wall popped up on Sunday's injury report with abdominal soreness, and he is trending toward sitting out with an issue he has not dealt with this season. If he can't go Sunday, Reggie Jackson would likely rejoin the rotation and serve as the backup point guard to Terance Mann.
