Celtic are leading Dundee 2-0 at half time as the Scottish Premiership champions look to keep up with league leaders Aberdeen.
Ronny Deila's side were energetic in the opening stages, with top scorer Leigh Griffiths hitting the side-netting from a free kick after Kris Commons was brought down just outside the area.
Dundee goalkeeper Scott Bain did well to keep out a Griffiths shot from six yards with 11 minutes gone, but the home side took the lead shortly after when Emilio Izaguirre pulled the ball back to Tom Rogic, who unleashed a pinpoint volley to put Celtic 1-0 up.
It was 2-0 just two minutes later, with Scotland international Griffiths controlling a Rogic cross and, after having his first attempt blocked, firing the ball into the back of Bain's net.
Rogic had two chances to grab his second of the game with just over 20 minutes gone, but watched as Bain was able to save both attempts.
Celtic keeper Craig Gordon was called into action after 42 minutes but was able to save a Gary Harkins free kick, with Kane Hemmings putting the rebound over.
James Forrest had an excellent run for Celtic as the half came to a close, but saw his shot crash off the Dundee bar to keep things at 2-0 at half time.
