Rotherham have signed midfielder Stephen Quinn, 19, on a month's loan from Sheffield United.
Millers boss Alan Knill saw Quinn score in United reserves' 7-2 win against Stoke and told the club's website: "He was the best player on the pitch.
"He is full of enthusiasm and never stops running. He will be an ideal replacement for Michael Keane."
Knill is likely to hand Quinn his first-team debut against Nottingham Forest on Saturday.
