Hull manager Nigel Pearson has refused to rule out a surprise return to the squad for goalkeeper Vito Mannone.
Mannone, on loan from Arsenal, has been effectively sidelined since late December with a thigh injury, but returned to full training with the Tigers this week.
Pearson, who has no new injury or suspension problems, said: "We'll have to wait and see, but I don't have any qualms about it (playing him).
"The attitude and mentality of the player is the most important thing and I'm just pleased to have him back with us."
Meanwhile, Nick Barmby is still recovering from a calf problem, but could be available for the Easter weekend.
Midfielder James Harper shook off a foot injury to play the full 90 minutes in the 1-1 draw at Swansea in midweek, while Matt Duke should continue in goal following Brad Guzan's return to parent club Aston Villa.
Doncaster defender Mustapha Dumbuya is hoping to return to contention.
The right-back, sidelined for nearly four months due to a knee injury, recently returned to the side, but missed the midweek home draw with Preston because of a tight hamstring.
James O'Connor, sidelined since mid-February due to a broken bone in his foot, and Matt Kilgallon returned to Rovers' starting line-up in midweek, so manager Sean O'Driscoll has plenty of options.
Another defender, Joe Mills, is still struggling with hamstring trouble, though, and leading goalscorer Billy Sharp, midfielder Martin Woods (both groin), plus defenders James Chambers and Adam Lockwood (both knee) remain sidelined.
Doncaster are eight points clear of the relegation zone and need to secure seven more from the five remaining games to guarantee another season in the Championship.
