Ross Tokely returns from suspension as Inverness go in search of a first league win since November.
Tokely is available again after missing the 3-3 draw with St Mirren, but Jonny Hayes, who returned from an ankle injury against the Buddies, is doubtful with a foot problem.
Grant Munro must serve the second game of a two-match ban, while Gavin Morrison and Kenny Gillett are back in light training and Graeme Shinnie, Nick Ross and Stuart Golabek remain out.
St Johnstone manager Derek McInnes has no fresh injury concerns.
Arvydas Novikovas is back in contention for the visit to the Caledonian Stadium.
He was cup-tied for the Scottish Cup win over Partick Thistle in Saints' last outing and is likely to be added to the squad for the weekend.
Inverness (from): Esson, Innes, Duff, Doran, Odhiambo, Foran, Rooney, Proctor, Duncan, Tuffey, Sutherland, Blumenshtein, Hogg, MacDonald, Hayes, Ross, Cox, Tokely.
St Johnstone (from): Enckelman, Duberry, MacKay, Anderson, Morris, Taylor, Craig, Davidson, Millar, May, Samuel, MacDonald, Novikovas, Maybury, Parkin, Caddis, Adams, Smith.
