Motherwell ensured Celtic's wait to be crowned Scottish Premier League champions will continue until at least Sunday after they defeated Dundee United 3-1 at Tannadice on Friday.
The Hoops, who need just one point from their final five fixtures, could have wrapped up the title without kicking a ball if Motherwell had slipped up against United.
However, a clinical display from Motherwell helped them claim all three points to reduce the gap at the top of the table to 12 points.
It means Celtic will now have the opportunity to clinch their second successive league title in front of their own fans in Sunday's match against Inverness Caledonian Thistle at Parkhead.
At Tannadice, Stuart McCall's side took the lead after just two minutes when Michael Higdon found the net with a strike from 25 yards.
Henrik Ojamaa doubled their lead in the eighth minute before Higdon rifled home his second of the game 10 minutes after the break.
Jon Daly sent a shot through the legs of Motherwell goalkeeper Darren Randolph to pull one back for United in the 69th minute, but the visitors held on for the win that keeps Celtic's title champagne on ice.
