Doncaster look set to be without Mustapha Dumbuya for the South Yorkshire derby clash with Barnsley.
The defender made his first start since the beginning of April in the goalless draw against Crystal Palace on Good Friday, but was withdrawn in the final 15 minutes after suffering a recurrence of his hamstring injury.
Dumbuya is rated as "touch and go" by manager Sean O'Driscoll so Shelton Martis, who came on as Dumbuya's replacement at the Keepmoat, is on standby to start.
Striker Billy Sharp is in a race to be fit before the end of the season following hernia surgery, but centre-half Adam Lockwood is making good progress after a knee operation.
But fellow defender James Chambers (knee) and midfield duo Martin Woods (hip) and Paul Keegan (knee) are all unlikely to feature again this term.
Rovers are chasing their first win in 10 league matches.
