Injuries have piled up in recent weeks, coinciding with a downturn in performances and results which has left Doncaster with just one win in eight games.
To make matters worse head coach Danny Schofield lost two more players to injury – James Brown and Caolan Lavery – during Saturday’s 2-0 defeat to Northampton Town.
Ben Nelson was also injured on international duty with England Under-19s.
No fewer than 11 Rovers players are potentially unavailable for this weekend’s visit of Crewe and at least five of them are out for the rest of the season.
Four of those missing – Harrison Biggins, James Maxwell, George Miller and Ro-Shaun Williams – have played more than 30 first-team games this term, while Brown, Charlie Lakin, Nelson and more recently Lavery have been regularly involved since arriving in January.
Jon Taylor and Ollie Younger would likely have been important players had they been fit.

. Louis Jones
Second-choice stopper Jones needed surgery on an ankle injury sustained in training. Speaking last month, Danny Schofield said: "It's difficult to put a timescale on it, but it’s going to be over eight weeks.” That could keep Jones out for the rest of the season. Photo: Howard Roe/ahpix.com
