Brian Stock and Jason Shackell are hoping to feature for Doncaster again before the end of the season.
Club captain Stock has been sidelined since February after undergoing surgery on a niggling back problem which had previously kept him out of action for four months.
The Wales international has been restricted to just 18 appearances this season as a result of the complaint, but appears to have finally got to the bottom of the issue.
Meanwhile, Shackell, who is on loan at the Keepmoat Stadium from Wolves, is closing in on a return to full fitness after sitting out the last 14 games with a groin injury.
Rovers boss Sean O'Driscoll said: "Brian is aiming to get back before the end of the season and Jason has got the target of the last game of the season.
"We won't push either of the players but both are motivated to get back before the end of the season.
"Brian is probably nearer but Jason is really determined to play some part in the last game of the season, which is good.
"His attitude has been first class, as has Brian's."
