Celtic held a two-goal lead heading into the final minutes but only managed to leave Tannadice Park with a point as it was held to a 2-2 draw by Dundee United on Sunday.
Miku opened the scoring for the visitors in the 69th minute while Anthony Watt looked to have sealed the win 10 minutes from time with Celtic's second of the match.
But United stormed back with Gary Mackay-Steven cutting the deficit in half in the 89th minute before an own goal from Efe Ambrose in the third minute of stoppage time gifted the home side a generous point.
The draw still sees Celtic climb to the top of the table, albeit on goal differential. The Hoops are level with Hibernian on 21 points, though Neil Lennon's men have one game in hand.
Dundee United is unbeaten in its last three league matches, improving to 13 points on the season.
