The Dons have confirmed the signing of former Hull FC duo Ryan Wilson and Alex Starling.
The two young players had been expected to arrive at the Keepmoat following their release from a few weeks ago.
Forward Wilson and centre Starling, both 20, had been lined up to spend the final year of their Hull contracts on loan with the Dons.
But Hull supremo Lee Radford felt he was unlikely to offer either man a new deal and opted to hand them their releases in order to allow them to join the Dons on a permanent deal, so as to not use up a significant chunk of the loan allocation.
Both men will play some part in the Dons’ final pre-season friendly against North Wales Crusaders on Sunday.
