Lee McCulloch's dramatic late equaliser in the Old Firm derby at Parkhead kept Rangers seven points clear at the top of the Clydesdale Bank Premier League after a 1-1 draw with Celtic.
After the home side had missed numerous chances and had a Marc-Antoine Fortune goal controversially ruled out for his challenge on Ibrox keeper Allan McGregor, Scott McDonald came off the bench to open the scoring with a 79th-minute header.
However, two minutes later McCulloch headed a Steven Davis corner past Artur Boruc to give the visitors an undeserved but welcome point.
