Stephen McGinn makes his 100th St Mirren appearance as the Buddies take on Ayr United at the Paisley 2021 Stadium.
The captain has been in fine form since rejoining the Saints in January and he'll be partnered by Stevie Mallan in the midfield.
Jack Ross has made two changes to the side that lost last week with Cammy Smith returning in place of John Sutton after being cup tied last weekend. Gary Irvine misses out due to suspension to be replaced by Stelios Demetriou.
We'll have all the action covered on our Twitter and Facebook pages, while expat supporters can watch the match live on St Mirren TV.
St Mirren: O'Brien, Stelios, Baird, MacKenzie, Eckersley, Mallan, McGinn, Magennis, Morgan, Smith, Loy
