Challinor told https://www.hartlepoolunited.co.uk: “Mason is a top player who I’ve worked with before, he was very unlucky with an arm injury when we had him at Fylde, he didn’t get the opportunity to show what he can do but I am excited for him. He is a physical lad who will hold the ball up well and link with other players and that’s exactly something you need in this league”.
