Michael Collins has handed Huddersfield a late pre-season boost by devoting his services to the League One side until 2010.
The 21-year-old's previous deal expired in 2009, but after a series of consistent performances last term and a call-up to Republic of Ireland's Under-21 ranks, Andy Ritchie's side were determined to keep him at the club.
"He was on a two-year deal but we were keen to extend it," Ritchie told the club's official website.
"I pushed for it and the board gave me their approval. Michael is an emerging talent as his Under 21 call-up shows and I am very pleased to secure his services until 2010 because we might have a problem keeping hold of him.
"He has got better and stronger over the past year and worked hard on his physique. That bit of brawn has made him an even better player."
Collins is a product of the Huddersfield academy, and after making 45 appearances last term, he is likely to feature regularly for Ritchie's side in the coming season.
