Johnny Russell's strike in first-half stoppage time has given Derby County a 2-1 lead over Huddersfield Town at the iPro Stadium.
Russell and Omar Mascarell both fired early shots goalwards and Jordan Ibe saw an effort cleared off the line as the hosts quickly asserted their dominance on the game.
They soon broke the deadlock though, as Ibe finished with aplomb from Jeff Hendrick's cut-back in the seventh minute.
However, Nakhi Wells reminded the home side of his attacking prowess in the 18th minute and Jack Butland had to tip the forward's low drive around the post.
Derby didn't heed the warning though, and Harry Bunn lashed home after a defensive mix-up to level the scores after 23 minutes.
Both sides continued to forge chances for themselves, with Derby's Chris Martin flicking the ball over the bar before Grant Holt nodded wide for the visitors.
Just as the half looked as though it was going to end all square, Russell pounced to slot the ball home after Martin's initial shot was saved to send his side into the break a goal ahead.
