HABIB Beye is a major injury concern ahead of tonight’s crucial trip to the Palace.
The Senegalese defender is nursing an ankle problem and may be forced to sit it out at Selhurst Park.
If Beye fails to prove his fitness, George Friend and Sam Hird are waiting in the wings to replace him.
Saunders must also decide whether to keep faith with an attack that has failed to score in their last two outings against Derby and Southampton.
Kyle Bennett could return to the starting line-up after returning from a toe problem as a second half substitute against the Saints.
Saunders’ first game in charge was a 1-0 win over the Eagles, courtesy of goal from John Oster that had more than a hint of fortune about it.
It was a moment that seemed to suggest Rovers’ luck had changed and the tide had turned.
Doncaster, however, head to Selhurst Park knowing if they do not take full advantage of their game in hand over fourth bottom Bristol City, they will be left with a very difficult task to stay in the Championship.
Rovers are currently five points adrift of safety with eight games left to play.
