Doncaster striker Mark McCammon is set for a one-month spell on the sidelines as a result of a hamstring injury.
McCammon has been struggling to shake-off the problem over recent weeks and has missed Rovers' last two games.
The 29-year-old sustained the injury during Doncaster's 2-0 defeat to Northampton on 7th September.
Rovers are now set to be without the services of McCammon for the visit of Cheltenham to the Keepmoat Stadium on Saturday.
"McCammon is going to be out a bit longer, probably three to four weeks," said a Rovers official.
