Christian Roberts has been out injured since Christmas, and isn't likely to return for at least another month.
On Loan striker Jamie Slabber has played well, but has yet to score for Swindon, and Rory Fallon has had it chances limited again this season.
Andy King said: "The only thing on my mind is that we need a consistent run of goals from now until the end of the season to push us into those play-off spots. I look at players all the time, but if things go well in coming weeks then I may not need to bring someone in."
