Kilmarnock are trying to hammer home their numerical advantage. They know that a second goal would completely deflate the 10-man visitors.

St Johnstone, however, are sticking to their principles, playing out from the back and keeping the ball on the deck.

Should be a fascinating afternoon ahead in the Rugby Park sunshine.

St Mirren manager Craig McLeish tells BBC Sportsound: "We've had a bit of illness going through the squad.

"Declan John played through it the other night and it probably just wiped him out. He was feeling a wee bit better this morning, so we thought we'd include him on the bench. Chris Mochrie is similar but feeling a wee bit better.

"It was maybe a wee bit flat on Wednesday night, although we still looked really solid and tough to play against, but we've had to mix things up today.

"We know there's going to be ups and downs and tough periods. It's about us all sticking together and still showing the same belief and confidence that we were showing when we were winning games at the start of the season.

"It's so tough. It's ruthless, you have to be at your absolute best every single week, you can't have an off-day or you'll get found out. It's exciting to be involved in, but it's also a bit chaotic."
