He has now re-signed on loan again until January 15 and has been given the green light to play in the FA Cup competition.
However, he cannot play in the forthcoming first round replay with Hereford as he was not eligible to play in the original tie.
He would also not be able to play against Leicester if the two clubs were to be drawn together.
De Vries scored one goal in five appearances during his first loan spell at Leeds.
