Crewe boss Dario Gradi is already without Nick Maynard as he recovers from a hamstring injury which was picked up in the win at Carlisle United.
So Gradi may turn his attentions to Lee Matthews or Pavol Suhaj to partner the clubs top scorer Luke Varney as the Alex look to take some sort of lead in the first leg of the Johnstone's Paint Trophy.
Doncaster come in tonights match in a rich vein of form with only one defeat in the last sixteen in the league.
So far Rovers have seen off the challanges of Huddersfield (2-1), Hartlepool (3-1), Accrington Stanley (2-0) and Darlington (2-0) to progress to the Johnstones Paint Trophy Northern Final.
