Clackstone, who was included in the Tigers’ first team squad during the opening weeks of this season, is currently on loan with League Two side Notts County. The Beverley-born 20-year-old (pictured) is capable of playing as a full back or centre back and has signed a one-year deal.
Also signing one-year deals are Development Squad members Will Annan and Adam Curry. Another born in Beverley, midfielder Annan has been with the Club for a number of years having originally joined at Under-13 level, while centre back Curry arrived at the Academy in November 2015 after impressing on trial from South Shields.
Completing the list of new contracts are Lewis Ritson and Tyler Hamilton, who are both celebrating their first professional deals. Both players started this season with the U18s, but more recently have stepped up to play for the U23s with one-year deals their reward. Ritson is a South Shields-born centre back, while Hamilton is a local lad who has progressed through the Academy since joining as an Under-9.
Commenting on the new deals, Academy Manager Jon Beale said: “I am delighted for Josh, Will, Adam, Lewis and Tyler. They have all made excellent progress in recent months and it is fantastic that they are all now set to continue their development with us.
“It is another significant step in their young careers, but they must all now continue to work hard and look to kick on again in the next 12 months.”
