Dumbarton 0-0 Heart of Midlothian

Hearts returned to the top of the Scottish Championship despite dropping their first points of the season at the home of Dumbarton.

Goalkeeper Danny Rodgers made some fine saves to keep Hearts at bay, denying Jason Holt and Osman Sow in the first half and Sam Nicholson in the second.

Chris Kane's header was the closest the Sons came, his header saved by Neil Alexander.

And, late in the game, Nicholson's header came back off the crossbar.

Robbie Neilson's side, who remain unbeaten but lose their 100% record, move a point clear of Rangers.
