Video: Celtic 1 St Johnstone 1
Celtic were held for the first time this season in a 1-1 draw with St Johnstone at Celtic Park.
The Hoops fell into arrears when Steven MacLean took advantage of goalkeeper Craig Gordon's failed attempt to clear.
But substitute Callum McGregor equalised with a low strike eleven minutes from time to ensure them a 53rd successive unbeaten domestic fixture.
Both Scott Sinclair and Mikael Lustig were later denied by the woodwork.
