Gary McDonald is back in St Johnstone's starting XI after returning from a knee injury for today's clash against Scottish Premiership champions Celtic at McDiarmid Park.
However, Tam Scobbie and Murray Davidson remain unavailable.
The Bhoys are without full-back Emilio Izaguirre, who has been given time off ahead of his participation at the World Cup with Honduras, while Greek forward Georgios Samaras has been struggling with a virus and also won't feature.
