Clint Hill scored a late equaliser as Rangers hit back to earn a 1-1 draw against leaders Celtic in the Ladbrokes Premiership at Parkhead.
Stuart Armstrong fired Brendan Rodgers' side ahead from outside the box 10 minutes before the break but Hill pounced from close range three minutes from time after Craig Gordon had made a good save from Emerson Hyndman.
It was only the second time this season that Celtic hadn't won a domestic match but they require only six more points to clinch the title.
