Centre-back Scott Cuthbert will be assessed ahead of kick-off having gone off midway through the first half of Tuesday`s Johnstone`s Paint Trophy win over Torquay complaining of dizziness, a reaction which carried over from a bang to his head against Dagenham last weekend.
His potential absence could leave the Robins light at the back with fellow defenders Alan Sheehan, Lecsinel Jean-Francois (both hamstring) and Callum Kennedy (ankle) already sidelined, along with star striker Charlie Austin (shoulder).
Midfielder Paul Caddis and striker Thomas Dossevi remain on international duty with Scotland`s Under-21s and Togo`s senior squad respectively.
On-loan wide man Matt Ritchie could make his league debut having impressed in the 2-0 midweek cup win following his switch from Portsmouth.
