Declan is a product of the under-19s and his performances earned him a full-time contract in 2014. He made his Super League debut just before his 20th birthday in a stunning 80-0 trouncing of Wakefield in April 2015 and went on to secure his place in our side for the next two months. An accomplished goal-kicker and touch-finder, he has landed a number of field goals to secure victories. He deputised for the injured Chris Sandow in the 2016 Grand Final against Wigan at Old Trafford and scored the first try. Declan was called into the England Knights squad in 2018 and kicked the goals in their two internationals in Papua New Guinea.
