The Welsh international, who joined us from Peterborough United in January, 2000, has been in excellent form this season and his decision to commit himself to us is great news for the club.
"In taking part in all but one of our matches this season, Simon has proved he has served his apprenticeship with flying colours and we are delighted he has established himself in the side," said Director of Football, David Pleat.
"Simon has an outstanding future with Tottenham and Wales and we are delighted he has shown his faith in us at the same time we have shown our confidence in him.
"We are also confident that our other similar young signings will progress in the same manner as Simon and will play a vital role in the club's future."
We are delighted to announce that 22-year-old midfielder Simon Davies has agreed a new five-year contract which will keep him at the club until 2007.
