St Johnstone v Celtic preview

St Johnstone manager Derek McInnes expects to name a similar side to the one who lost to Celtic midweek.
Murray Davidson took a knock to his ankle but should be fit as Saints attempt to make amends for their Co-operative Insurance Cup exit.
Graham Gartland and Kevin Moon (both knee) and Jody Morris (rib) are still all out.
Celtic striker Gary Hooper is a doubt for the trip.
The former Scunthorpe played picked up a metatarsal injury in the Co-operative Insurance Cup quarter-final win over the Saints in Perth on Wednesday night.
Skipper Shaun Maloney, who missed the trip with an eye injury, is also a doubt.
Kick-off is 12pm.
St Johnstone (from): Smith, Maybury, Grainger, Duberry, MacKay, Craig, Davidson, Millar, Samuel, Haber, Jackson, Caddis, Parkin, Rutkiewicz, MacDonald, Enckelman, Myrie-Williams, May.
