St Mirren have recalled midfield duo Gregg Wylde and Isaac Osbourne for their Scottish Premiership meeting with in-form Aberdeen.
Coach Gary Teale has opted to pack the midfield in the absence of striker Steven Thompson, who could miss up to four weeks following a hernia operation.
Table-topping Aberdeen have kept the faith in the side that won 2-0 at Motherwell in their last outing, with absentees Clark Robertson and Craig Storie failing to return to fitness in time.
Willo Flood was pressing for a start following his appearance as a substitute last weekend, but has been left out entirely.
St Mirren: Ridgers, Naismith, Kelly, Tesselaar, Goodwin, Osbourne, McLear, Mallan, McGinn, Wylde, McLean
Aberdeen: Brown, Logan, Considine, Taylor, Reynolds, Rooney, McGinn, Hayes, Pawlett, Goodwillie, Jack
