No Navarro for Robins
Swindon look set to be without Alan Navarro for the clash with Crewe.
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.
Steve Phillips and Luke Murphy remain major injury doubts for Crewe.
Alan Martin started between the posts in Saturday's 2-1 defeat to leaders Doncaster at Gresty Road, with Phillips laid low due to a dead leg suffered during the loss at Brentford in midweek.
Skipper Murphy sat out at the weekend as he continues to nurse a groin problem that sidelined him in the weeks leading up to his starring role in Alex's 2-0 Johnstone's Paint Trophy triumph over Southend at Wembley.
Rookie centre-back George Ray made his full debut against Rovers and will hope to continue, although boss Steve Davis may return to a back four after the Railwaymen lined-up 3-5-2 last time out.
Midfielder Abdul Osman must serve the second game of a two-match suspension for collecting 10 yellow cards this season.
Top scorer Mathias Pogba (thigh) will miss the remainder of the season, while defender Adam Dugdale remains on compassionate leave.
