Emerging as a first grader with nine Super League appearances in 2007, the England Academy full back has primarily been used in a wing position for the Wolves' first team. An elusive runner who is stronger than his build suggests, Riley is Warrington born and joined the club from Woolston Rovers. He graduated through Warrington Service Area teams and came through the Wolves scholarship scheme to feature in the Wolves Junior Academy Grand Final successes in 2003 and 2004. Represented England U17 against the Australian Institute of Sport in 2005, the same season he made a try-scoring debut for England Academy against France.
