With Dumbarton guaranteed a second placed finish in cinch League Two this season, the Sons dates for play-off fixtures have become a little clearer.
Dumbarton will contend against the third placed team in the league which at the moment is Annan Athletic, though could still turn out to be East Fife.
Just a point separates the pair with one league game to go as Annan travel to Stenhousemuir and East Fife visit Forfar Athletic on Saturday.
The tie will be a two-legged affair, the first of which will take place away from home on either Tuesday May 9 or Wednesday May 10, just a few days after the conclusion of the regular season against Stranraer on May 6. Kick-off will be at 7:45pm.
The return leg will be at the Dumbarton Football Stadium on May 13 with the winner of the two-legged tie advancing to the final to take on the winner of the other semi-final between fourth in League Two and ninth in League One, which is Clyde. Kick-off will be at 3:00pm.
The first leg of the final will take place on Tuesday May 16 with the lowest-ranked of the four teams that contest in the play-offs at home in the first leg. Kick-off is at 7:35pm with the game broadcast live on BBC ALBA.
The second leg will kick-off at the same time on Friday May 19, also live on BBC ALBA, with the highest-ranked team at home.
Admission details for both legs of our semi-final will be released in due course.
