The hosts, who occupy fifth position, are hoping to remain in the top half of the table, while Kilmarnock are languishing in 11th place.
Match preview

After picking up seven points from three matches, St Mirren were brought back down to earth when they face Rangers at Ibrox last weekend.
St Mirren came from behind on two occasions thanks to a Mark O'Hara brace, but three Rangers goals in the final 11 minutes condemned Stephen Robinson's side to a disappointing 5-2 defeat.
The Buddies will have to pick themselves up as they look to secure their first top-half finish in the Scottish Premiership since 1985.
St Mirren know that a win will be enough to end their 38-year wait, but they could still advance into the top six of the split even if they draw or lose, depending on the result of the two games involving Hibernian and Livingston.
Having lost just three of their 16 home league games this season, Robinson's side will be confident of claiming a positive result on Saturday.
Like their hosts, Kilmarnock also head into the weekend's encounter off the back of a heavy defeat, after they were thumped 4-1 by Celtic last Sunday.
Kilmarnock are guaranteed to be in the bottom six for the final stretch of the season, with Derek McInnes's side residing in the relegation playoff spot.
Although they are only in the bottom two on goal difference, Kilmarnock are also just one point better off than basement side Ross County.
Killie have struggled at both ends of the pitch this season, registering just 27 goals in 32 games to leave them as the joint-lowest scorers in the top flight, while they share the worst defensive record with Dundee United after shipping 56 goals this term.
With two points to show from their 16 away games, Kilmarnock are the only Scottish Premiership side yet to win an away league game in the 2022-23 campaign, and they will need to improve on their road in the run-in if they are to move out of the bottom two.
