Scottish Premier League football side Celtic haven't been able to close the gap on League leaders Rangers with the Old Firm derby finishing in a 1-1 stalemate at Celtic Park.
Super sub Australian Scott McDonald looked to have sealed a well-deserved win for Celtic when the Socceroo headed past Allan McGregor with 11 minutes left.
But Lee McCulloch nodded in the equaliser two minutes later with his side's first shot on target before McGregor produced a superb save to deny Georgios Samaras a late winner.
