League Two side Bury have signed Bolton Wanderers full-back Joe Riley on a two-and-a-half year deal.
The 23-year-old spent five months on loan at Oxford earlier this season where he made 28 appearances.
The Wanderers academy product was out of contract at the end of the season at the Macron Stadium.
"Joe Riley, who we have been tracking for some time, is another fantastic addition to the group," said Shakers manager David Flitcroft.
"He loves to drive forward from full-back and has a controlled aggression about his work. He is both athletic and dynamic and will offer us both great quality and energy in the wide areas of the pitch."
