The skilful striker is on loan from the Robins until January and is likely to be replaced by Craig Beattie although Cedric Van der Gun will be hoping to get his full debut after coming off the bench in Saturday's defeat at Preston.
Manager Paulo Sousa also has a number of injury concerns to deal with as he aims to get his side's season on track following three defeats from their opening six games.
Striker Stephen Dobbie (ribs) is out, as are midfielder Darren Pratley (shoulder), winger Thomas Butler (hernia) and forward Guillem Bauza (knee).
Angel Rangel and Gary Monk serve the final game of their respective three-game suspensions but Ferrie Bodde could be handed his first start since November after a knee injury.
Joe Allen (hamstring) and Fede Bessone (groin) are also pushing to be involved from the off.
