Riley loaned to Oxford
Oxford have completed the signing of full-back Joe Riley on a short-term loan deal from Bolton.
The Wanderers' academy prospect will spend the first half of the season on loan with the League Two club, returning on New Year's Day.
Riley has made just nine professional appearances since breaking into the first team in 2011. He suffered a serious knee injury last summer, which kept him on the sidelines for the majority of last season.
