Derby's Tom Huddlestone will not join Tottenham until the summer so he can play a part in the Rams' promotion bid.
Huddlestone staying on will boost Derby's promotion hopes
They are currently fifth in the Championship and will keep the 18-year-old defender until the summer, when he will join Tottenham for £2.5m.
"It's important we prevent the move from disadvantaging our quest for success," said Derby chief executive Jeremy Keith.
"He is still a Derby player who remains committed to the club."
An England U17 international, Huddlestone broke into the Rams' first team at the age of 16.
He was their joint top-appearance maker last season with 44 starts, and has proved his versatility this term, playing in a number of different positions.
