Rangers stumbled to a 1-1 draw at Motherwell in their opening game of the Scottish Premiership season on Saturday, as Russell Martin's men conceded a late equaliser at Fir Park.
The Glasgow giants, who secured a place in the third round of Champions League qualifying earlier this week, could not give new manager Martin a winning start to the league campaign.
James Tavernier put Rangers into a 14th-minute lead before Motherwell started to create chances.
The visitors kept them at bay until the 87th minute when English midfielder Emmanuel Longelo grabbed the home side a deserved point.
"I think we were lucky with what we got, Motherwell were really good," said former Southampton boss Martin.
"The thing I can't accept is, whatever the tactics are, we got outfought and they were braver than us to play in certain moments."
Elsewhere, Kilmarnock dropped a 2-0 lead over Livingston to draw 2-2 after George Stanger was shown a second-half red card.
On Sunday, Celtic kick off their title defence against St Mirren at Parkhead.
Brendan Rodgers' side romped to the championship last term, finishing 17 points clear of second-placed Rangers.
