Doncaster are expected to be without teenage midfielder Ryan Mason for the clash at Watford.
Mason, 18, has returned to parent club Tottenham for treatment on a back problem and Rovers manager Sean O'Driscoll could be forced to draft in cover on loan.
Defenders Wayne Thomas (knee), Byron Webster (metatarsal) and James Chambers (knee) remain sidelined.
But O'Driscoll will be boosted by the return to fitness of skipper Brian Stock (back) - he withdrew from the Wales squad last week - and defender Adam Lockwood, who have both benefited from the break for international matches.
Rovers, who bounced back from a recent 4-0 drubbing at Cardiff by defeating Hull 3-1 in their last league match, could climb into the top six with victory.
