The former Brighton midfielder, who was an unused substitute in the 2-0 defeat at Sheffield United on Saturday, has gone for a scan on a hamstring injury he picked up against MK Dons last week.
Manager Kevin MacDonald said he hoped it would not be a serious injury but the club will know more after the scan.
Meanwhile Tommy Miller is not running yet as he looks to return from a calf problem, ruling him out of the County Ground visit of the Railwaymen.
Nathan Thompson, Troy Archibald-Henville, Miles Storey, Jay McEveley, Aaron Oakley and Louis Thompson are all out for the rest of the season.
Swindon are currently in the last npower League One play-off spot, just one point clear of seventh-placed Walsall.
