ABC executives have decided to change the network's Wednesday night line-up to protect new series The Knights of Prosperity.

Knights has struggled to compete against FOX's American Idol in recent weeks and will now be moved back half an hour to 8.30pm. According to Jim will shift to a new 9.00pm slot, while George Lopez continues at 8.00pm.

New comedy show In Case of Emergency will remain in its current 9.30pm slot, however, staying in competition with Idol.
