Derby County have come from a goal down to draw level with Huddersfield Town at 1-1 as the sides go into the break at the iPro Stadium.
However, it was the away team who took the lead after 14 minutes when Nakhi Wells tapped home from close range.
Wells almost made it 2-0 shortly after, but Lee Grant spared the blushes of Keogh, whose underhit pass back to his goalkeeper granted the Huddersfield striker with another chance.
The lead lasted little more than 10 minutes, though, as Russell drew Derby level with a composed finish after an incisive through-ball.
On the stroke of half time, Bamford could have put Derby ahead, but the youngster blazed over the bar from close range.
