Heaton returned to the side last week as City ended a four game winless streak with a 4 - 1 victory over Derby County. Heaton missed all four matches in March that City picked up just two points from.
Apart from the long term injuries to Michael Chopra and Mark Hudson City should have no other injury issues for today's game.
Doncaster Rovers are boosted by the return to fitness of defenders James Chambers (hamstring) and James O'Connor (foot), who could both feature.
Skipper Brian Stock limped off with an ankle injury against Bristol City but is expected to be passed fit.
Kick off is at 3:00pm.
