The second leg of the Ladbrokes Premiership play-off final takes place on Sunday, live on BT Sport with a 3.30pm kick-off.
Livingston take a 2-1 lead along the M8 to The Energy Check Stadium at Firhill after beating Partick Thistle at the Tony Macaroni Arena on Thursday evening.
David Hopkin steered Livi to the League 1 title last season and they are now 90 minutes away from a return to the top flight for the first time since 2005/06.
Alan Archibald's Thistle side finished sixth in the Premiership last season but their five-year stay is now under threat after a first-leg loss in West Lothian.
There is no away goals rule in the play-offs so extra time, and penalties if required, will settle the outcome if the scores are level after 90 minutes.
The referee for Sunday’s game is John Beaton.
