Two late goals from Ross Draper were not enough to stop Celtic, as the Hoops overcame Inverness CT 4-2 at the Caledonian Stadium this afternoon.
Elsewhere, Richard Brittain's 72nd-minute penalty was enough to give Ross County the points away to Dundee and goals from Paul Hanlon and Eoin Doyle gave Hibernian a 2-0 win at home to St Johnstone.
Kilmarnock ran out 3-1 winners against Dundee United.
