Chris Sutton and Bobo Balde could join Celtic’s bid to move five points clear of Rangers with victory over Aberdeen in the Bank of Scotland Premier League tomorrow.
The influential Englishman injured a foot and the defender hurt a leg in the 4-0 win over Livingston in midweek but they are recovering.
Goalkeeper David Marshall, who kept a clean sheet on Wednesday, looks like continuing in goal with Robert Douglas still recovering from a groin strain.
Didier Agathe continues his fight for full fitness after a long-term groin problem and could be on the bench.
Provisional squad: Marshall, Henchoz, Balde, Sylla, Varga, Sutton, Petrov, McGeady, Thompson, Hartson, Lambert, Lennon, Bellamy, Fernandez, Valgaeren, Maloney, McNamara, Hedman, Wallace, Agathe.
