Dundee United must beat Dundee at Dens Park tonight, live on BT Sport at 7.45pm, to avoid relegation from the Ladbrokes Premiership.
Second-bottom Kilmarnock's 4-0 win against Hamilton Accies at New Douglas Park on Saturday moved them 11 points clear of Mixu Paatelainen's men, who have four games left to play.
Dundee came from behind to win 2-1 in the last meeting at Dens Park on January 2 while both matches between the city rivals at Tannadice this season ended in dramatic 2-2 draws.
Dundee United were last relegated in 1994/95 but bounced straight back the following season, beating Partick Thistle in the play-offs after finishing runners-up to Dunfermline Athletic.
