Dumbuya Mustapha chance
Doncaster defender Mustapha Dumbuya is hoping to return to contention for the crucial relegation clash with Crystal Palace.
Dumbuya has missed the last two games due to a calf strain but is expected to be added to Sean O'Driscoll's squad for the visit of Palace, who are two points behind fifth-bottom Doncaster in the table.
O'Driscoll is unlikely to make too many changes to the side beaten 3-1 at Hull last week. He has no new injury or suspension problems but there are no others ready to return.
Striker Billy Sharp is in a race to be fit before the end of the season following hernia surgery and centre-half Adam Lockwood is making good progress after a knee operation.
But fellow defender James Chambers (knee) and midfield pair Martin Woods (hip) and Paul Keegan (knee) are all unlikely to feature again this season.
Rovers are chasing their first win in nine league matches.
