Scott Brown and Glenn Loovens scored to give champions Celtic a 2-1 victory at Inverness on Saturday and open a three-point lead over Rangers in the Scottish Premier League, reports CNN.
Rangers' game against Dundee United was postponed after the death on Thursday of United chairman Eddie Thompson.
That means Walter Smith's side now has a game in hand on their Glasgow rivals, who have 22 points from nine games.
Celtic went to Inverness without injured strikers Giorgios Samaras and Jan Vennegoor of Hesselink but cruised into a two-goal lead in the second half.
Brown turned home a cross from Lee Naylor early in the second half and Loovens made it 2-0 in the 65th minute when he headed in Barry Robson's pass
Inverness pulled a goal back in the 69th when Ross Tokely's cross was met by Adam Rooney, who passed for Garry Wood to force the ball home.
Third-placed Kilmarnock edged Motherwell 1-0 with an 89th-minute goal by Craig Bryson. Aberdeen won 1-0 at bottom-of-the-table Falkirk thanks to Lee Miller's 48th-minute header, while St Mirren secured a 2-1 triumph at Hamilton.
