Dumbarton 2-1 Falkirk
Falkirk's Scottish Championship title hopes suffered a blow after Dumbarton came from behind to beat the Bairns.
Rory Loy tucked away his 14th goal of the campaign to put Gary Holt's side ahead at half-time.
But Mitchel Megginson levelled in the second half, converting Colin Nish's cross.
And Jordan Kirkpatrick completed the turnaround when he fired past Michael McGovern from the edge of the penalty box.
Falkirk slip to third in the table and are now six points off leaders Dundee.
