Defender Aaron Lescott sustained a hip injury in Tuesday's dismal 5-0 loss at Leyton Orient and was withdrawn after 33 minutes, while midfielder Chris Lines also suffered an injury in that game.
Lines did manage to complete 90 minutes at Brisbane Road though, despite an abdominal problem that will require a scan on Friday.
Ben Swallow and Dominic Blizzard are the likely replacements should Lescott and Lines not make it.
Boss Paul Trollope is not expected to make wholesale changes despite the shocking show against Orient that stretched Rovers' winless run on the road to nine games.
Trollope, who has no other injury or suspension problems, is expected to try and strengthen his squad when the emergency loan window reopens on Monday.
