Celtic restored their six-point lead at the top of the Ladbrokes Premiership with a 4-1 win over Ross County in Dingwall on Sunday.
Tom Rogic broke the deadlock with a fine strike late in the first half and Leigh Griffiths scored twice early in the second period to take his tally for the season to 13 Premiership goals.
Tony Dingwall pulled one back for the Staggies but Nir Bitton added a fourth goal for Ronny Deila's men with 15 minutes remaining at the Global Energy Stadium.
