Louie Sibley’s last-minute winner gave Derby a 1-0 home victory over stubborn Stevenage to boost their automatic promotion hopes in League One.

With top scorer James Collins out with a knee injury, Derby lacked a presence up front but Sibley finally found a way through in the last minute of normal time.

The victory moved Derby three points clear of third-placed Bolton.

It was Stevenage who came closest to scoring in a goalless first half.

Joe Wildsmith missed a corner and Sonny Bradley had to clear off the line in the 31st minute and Wildsmith rescued Derby soon after when the hosts failed to deal with a long throw and the goalkeeper stopped Jordan Roberts’ shot on the turn.

Derby did not register a shot on goal in the first half and they continued to struggle until Kane Wilson surged forward in the 68th minute and played Nathaniel Mendez-Laing in but he fired wide.

Max Bird was denied by a superb Taye Ashby-Hammond save in the 77th minute but Derby struck late on.

Mendez-Laing cut in from the right and set up Sibley who finished first time from 12 yards.
