St Mirren host Aberdeen in the William Hill Scottish Cup with a place in the semi-final up for grabs.
FORM
St Mirren - WWLDDD
Aberdeen - LWLWDL
Saints path to the quarter-finals has seen Jim Goodwin's side beat Broxburn Athletic in the fourth round and Motherwell in the fifth round.
The Buddies eventually sealed a comfortable 3-0 win over Broxburn Athletic in January with Jon Obika scoring either side of a Danny Mullen strike.
That win over Broxburn set up a fifth round clash with fellow Ladbrokes Premiership side Motherwell at the Simple Digital Arena. Motherwell took a first-half lead, but Alex Jakubiak's first goal for the Saints ensured a replay at Fir Park.
Despite Saints being 4-1 ahead at half-time in the replay, it would take penalty kicks to separate the two sides with Jamie McGrath, Kyle McAllister and Obika netting in the shoot-out as the Buddies progressed.
Aberdeen's route to the last eight has been fairly similar to that of Saints. The Dons needed an 86th minute Sam Cosgrove penalty to see off League One side Dumbarton at Pittodrie in January.
The Dons were then paired with Kilmarnock in the fifth round in an all Premiership clash. Derek McInnes' side were held 0-0 at Pittodrie with the game going to a replay.
The replay, which took place 24 hours after Saints' replay with Motherwell, was just as dramatic as St Mirren's as the Dons progressed in extra-time after a 4-3 win.
St Mirren come into tomorrow night's match on the back of an important three points against Motherwell in the Ladbrokes Premiership on Tuesday night. Despite Liam Donnelly giving Motherwell the lead, second-half goals from Jon Obika and Ilkay Durmus gave the Buddies their first league win of 2020.
Aberdeen, meanwhile, lost to Ross County at Pittodrie on Saturday. Curtis Main put Aberdeen 1-0 ahead, but the Dons were reduced to 10 men when Dean Campbell was given his marching order. County took advantage with Billy McKay scoring twice to consign Aberdeen to defeat.
PREVIOUS
Tomorrow's match will be the fourth meeting of the two this season.
Both sides have won one match each while the other ended in a draw.
Ilkay Durmus' early goal was enough to separate the teams in the first meeting of the season way back in August as the Buddies won 1-0 at the Simple Digital Arena.
Saints were narrowly beaten on their trip to Pittodrie in November as Aberdeen edged the match 2-1. Jon Obika had equalised for the Buddies after Sam Cosgrove had given the Dons an early lead. Niall McGinn put Derek McInnes' side back in front while Tony Andreu missed a late penalty for Saints.
The sides couldn't be separated when Aberdeen visited Paisley in January as the game finished 0-0 at the Simple Digital Arena.
St Mirren last faced Aberdeen in the Scottish Cup in 2018. Despite Gavin Reilly scoring his 21st goal of the season for the Buddies, Aberdeen would run out 4-1 winners thanks to goals from Adam Rooney, Ryan Christie (x2) and Gary Mackay-Steven.
