St Johnstone v Celtic preview
St Johnstone manager Tommy Wright is expected to rest some players for the visit of Scottish Premiership champions Celtic with the William Hill Scottish Cup final in mind.
Frazer Wright was left out of Saturday's defeat at Motherwell and others may follow.
Gary McDonald is pushing for more involvement to boost his fitness after coming back from a knee injury off the bench at Fir Park. Long-term injury victims Tam Scobbie (ankle) and Murray Davidson (knee) remain out.
Neil Lennon is likely to ring the changes for Celtic's Scottish Premiership clash with St Johnstone at McDiarmid Park on Wednesday night.
Left-back Emilio Izaguirre will play no further part for the champions this season after being allowed time off before meeting up with Honduras ahead of the World Cup and Lennon is hoping to give starts to number two goalkeeper Lukasz Zaluska plus forwards Dirk Boerrigter, Teemu Pukki and Amido Balde.
Midfielder Nir Biton and wide man James Forrest remain out with groin injuries, while Greek striker Georgios Samaras has failed to shrug off his illness.
