"Dan's future development opportunities would have been limited at Newcastle due to the strategic plan for our development squads," Beardsley said.
"I feel that given the right opportunity, Dan can have a very good future in the game and will develop further into a very good player. Dan's size and strength does not reflect his young age and he has a very good goalscoring record.
"I have had the pleasure of working with Dan for a number of years and his approach and attitude to both training and games has been first class."
