Three in a row
Clinton Morrison converted an 85th. minute penalty to give City their third consecutive win.
It was a desrved win for the home club against a very well organised Doncaster Rovers side who at times played some attractive football but created little.
In the first half the Sky Blues hit the woodwork three times, which included Leon Best hitting the post when missing from the penalty spot.
City dominated the second-half and were rewarded for their efforts when Morrison converted their second penalty after a foul on Garry Madine.
