Half-time: Leeds United midfielder Paul Green returns to haunt Derby County after Conor Sammon opener
A GOAL from former Derby County midfielder Paul Green on the stroke of half-time cancelled out Conor Sammon's opener as the Rams went into the break level at 1-1 with Leeds United.
Sammon opened the scoring with his fifth goal of the season after a quarter of an hour.
But Green equalised in the 45th minute on his first return to Pride Park.
Derby boss Nigel Clough named an unchanged side after midfielder Craig Bryson (knee) and defender Gareth Roberts (calf) were again ruled out by injury.
As a result, James O'Connor continues at left-back and Jeff Hendrick keeps his place in the middle of the park.
There was one change on the bench - Conor Doyle replacing Michael Hoganson after recovering from emergency surgery on his appendix.
Sammon chased down his own flick-on in the ninth minute and keeper Paddy Kenny raced out of his goal but cleared against his own player, though was relieved to see the ball bounce wide of the unguarded net.
From Jacobs' resulting corner, Theo Robinson headed goalwards but the ball deflected over off a Leeds player.
Ross McCormack's free kick cleared the bar in a brief spell of Leeds pressure - but the Rams went ahead in the 15th minute.
Robinson's quickly taken free kick found Will Hughes, who threaded a pass to Sammon.
The striker controlled the ball on the edge of the box, went past Lee Peltier and his low shot wrong-footed Kenny on its way into the net.
Derby looked to press home their advantage and, in the 24th minute, Robinson combined well with Sammon but Kenny blocked at his feet, from a tight angle.
Hendrick went in high on Ryan Hall after 36 minutes but escaped with a yellow card.
With half-time approaching Hughes' cross from the left was sliced into the side-netting by Leeds defender Tom Lees.
But the visitors were level just before the break.
A cross from the left was nodded down by Luciano Becchio and Green nipped in to turn the ball past Adam Legzdins from close range.
