Hull 0-0 Doncaster
Hull missed the chance to close on the top two teams in the Championship after a goalless draw at the KC Stadium.
Doncaster goalkeeper David Button, on-loan from Tottenham, had an inspired evening with a string of fine saves.
He kept out Corry Evans, Cameron Stewart and several Robert Koren efforts, while Matty Fryatt fired wide.
In a rare Rovers attack El-Hadji Diouf's curling shot was tipped over by Vito Mannone, but the visitors ended a run of six successive away defeats.
