Hearts have failed to make possession count in their first half against Dumbarton, with the two sides deadlocked at half time.
Prior to kickoff at Tynecastle, a minute's silent was observed for former Hearts and Scotland legend Dave Mackay, who passed away just over a week ago.
Hearts started strongly, but a defensive mistake allowed Chris Duggan through for the visitors. However, the striker failed to capitalise, sending his volley just wide.
Duggan continued to threaten for Dumbarton, angling a shot to the near post which forced a save from Neil Alexander.
Jamie Walker nearly opened the scoring after Osman Sow sent him through, but his shot struck the side-netting.
