Ross County have been denied their first ever win in the Scottish Premier League after Kris Commons's late equaliser salvaged a point for Celtic at Victoria Park.
After a goalless first half, Richard Brittain struck just four minutes after the restart to put County ahead.
Charlie Mulgrew nearly grabbed an equaliser for the visitors on 64 minutes but his effort came back off the crossbar.
It was a similar story for the home side when Brittain also found the woodwork with nine minutes to play.
However, Neil Lennon's side earned themselves a point in the second minute of added time thanks to Commons.
