Doncaster are waiting to discover the extent of the injury captain Ritchie Wellens sustained against Birmingham.
However, the club are optimistic the problem is not too serious after the midfielder was replaced by Martin Woods at half-time during the 1-1 draw at St Andrew's on Tuesday night.
Wellens was taken off as a precautionary measure after feeling his back and thighs tighten.
He will be assessed by Rovers' medial team ahead of Saturday's game at Bolton.
The 33-year-old has made 18 appearances in all competitions for Doncaster since rejoining the South Yorkshire club in the summer.
