The 18-year-old defender has joined up with Reece Gray, and will stay until January.
D'Arcy has appeared once for the Rochdale first team when he made his professional debut on 27 April 2013 in a 1–0 victory against Plymouth Argyle.
D'Arcy has replaced Glenn Belezika, who has returned to Oldham Athletic following the expiry of his loan.
We'd like to offer D'Arcy a big Ewen Fields welcome.
