Highly-rated Huddersfield Town defender joins York City on loan
The 20-year-old left-back signed a new three-year contract with the Terriers in the summer but is yet to play for the first team.
Daley started out as a winger in Port Vale's academy but was moved deeper when he joined Huddersfield in 2019.
His loan spell initially runs until January 2, by which time the transfer window will be open.
Daley has been registered in time to face Maidenhead on Saturday in 19th-placed York's next Conference match.
