Spoils shared in cagey Old Firm derby
Celtic came from behind to deny Rangers a third consecutive Old Firm victory as Adam Idah's second-half leveller earned a 1-1 draw at Ibrox.
Brendan Rodgers's side, which wrapped up the Scottish Premiership title after its win over Dundee United last week, maintained a 17-point lead over its fierce rival.
The host side almost went in front with just two minutes on the clock, but Leon Balogun's close-range header from James Tavernier's corner clipped the crossbar.
Barry Ferguson's team had the ball in the back of the net when another teasing Tavernier set-piece was met with a powerful header by Nicolas Raskin in the 25th minute.
The goal was chalked off, however, for offside against Raskin, who had just strayed beyond Celtic's defensive when the ball was whipped into the penalty area.
Rangers did take the lead in the 44th minute when Mohamed Diomande's pass was brilliantly dummied by Vaclav Cerny, allowing Cyriel Dessers to finish past Viljami Sinisalo.
But Celtic restored parity 12 minutes after the restart when Idah's deflected shot found a way past Liam Kelly, though the goal was initially ruled out for offside.
However, that decision was overturned after a VAR review, with Daizen Maeda ruled not to have impeded Kelly's line of sight when Idah's effort found its way into the net.
Maeda then had a glorious chance to snatch all three points in the last minute of stoppage time, but he was denied by the legs of Kelly as he tried to round the Rangers goalkeeper.
