Brian Graham opened the scoring for Ross County

Ross County moved into third in the Premiership as leaders Aberdeen lost their third straight league game.

Brian Graham put the hosts ahead after Paul Quinn's challenge on Ricky Foster only pushed the ball into his path.

He doubled the lead with another Quinn assist, the Dons defender misjudging the flight of the ball and heading to Graham to finish past Danny Ward.

Niall McGinn hit a post for Aberdeen and Adam Rooney was twice denied, but they were well beaten in Dingwall.

The result means champions Celtic can go top with a draw against Motherwell at Fir Park on Saturday.

Aberdeen manager Derek McInnes made four changes to the team thumped 5-1 by St Johnstone before the international break.

But they did not look too sure at the back in the early exchanges as Ross County threatened through Ricky Foster on the left and the in-form Liam Boyce down the middle.

Boyce twice twisted clear in the visitors' penalty area but produced shots that failed to test Ward.

At the other end, David Goodwillie, preferred up front to Adam Rooney, looked lively and went close with an audacious overhead kick before hitting a left-foot shot across the face of Gary Woods' goal.

It was a game played at a really high tempo with the Staggies looking the more dangerous side - as they showed when Graeme Shinnie was forced to block an Andrew Davies header on the goal-line after 23 minutes.

Foster and Boyce combined, the former picking out the latter with a diagonal cross from deep. His header was a textbook effort towards the bottom right-hand corner, but Ward pulled off an impressive diving save.

However, there was not much the man on loan from Liverpool could do to prevent the home side finally taking the lead.

Foster dribbled into the Aberdeen penalty area then seemed to lose his way, but the ball broke into the path of Graham, who clipped in his first league goal for County.

Aberdeen resumed after half-time in a positive manner, but they were hit by a counter-attack goal minutes into the second period.

Boyce beat Ash Taylor to flick a header on and Quinn misjudged the flight of the ball. That allowed Graham to run through on goal and finish at the second attempt.

McGinn was then denied by the post for the visitors, with Rooney having his shot from the rebound cleared off the line by Jamie Reckord.

If that was a let-off for Woods then the County goalkeeper played a significant part in maintaining their two-goal advantage with a brilliant save to deny Rooney.

At the other end, Boyce continued to have a miserable night in front of goal - shooting over the bar when it looked easier to hit the target - then mis-hit a shot when clean through on goal.

He was eventually substituted to give Dutch signing Alex Schalk a brief run-out along with the fit-again Craig Curran on a night with plenty positives for McIntyre.
