Ross County were promoted to the Clydesdale Bank Premier League after nearest rivals Dundee were held to a 1-1 draw by Queen of the South.
Dundee needed to win to delay County's Irn-Bru First Division title celebration but Queens defender John Potter cancelled out Stephen O'Donnell's opener in the 82nd minute.
O'Donnell opened the scoring with a deflected strike from long range in the 53rd minute at Dens Park but his former St Mirren team-mate Potter headed home Daniel Carmichael's cross following a half-cleared corner. The draw left Dundee 14 points behind the leaders with four games left.
