St Johnstone loanee Brian Graham will lead the attack against Dundee this afternoon following his goalscoring substitute appearance in the 1-0 win over Motherwell.

Graham is one of three changes for the Saints, with manager Tommy Wright also handing starts to Michael O'Halloran and Frazer Wright.

Dundee are without the services of striker Peter MacDonald, defender Willie Dyer and midfielder Kevin Thomson, but recent signing David Clarkson has been granted clearance to play, and takes up a place on the bench.

Clarkson, who has been capped twice for Scotland, joined Dundee earlier this week following a spell with Bristol Rovers.

St Johnstone: Mannus, Anderson, Mackay, Wright, Easton, O'Halloran, McDonald, Brown, Wotherspoon, Millar, Graham

Dundee: Letheren, Irvine, McPake, Konrad, McGinn, Ferry, McGowan, Roberts, Harkins, McAlister, Stewart
