Dennis Greene has moved to bolster his defensive ranks ahead of Saturday’s Buildbase FA Trophy trip to Witton Albion with the acquisitions of two players from the National League strugglers.
Both players joined the Minstermen in the summer, with Clappison (22) beginning his career at Hull City while Robinson (23) switched from Irish side Crusaders.
Clappison and Robinson are both eligible to make their United debuts at the weekend.
