Dons chief executive Carl Hall has expressed his disappointment at the decision to dock the club three points and insists an appeal will be lodged immediately.
The Dons suffered the points deduction yesterday after being found guilty by an independent operational rules review tribunal of fielding an ineligible player.
The tribunal ruled the club had breached the RFL’s rule B3.17 which insists dual registration players with a salary cap value of more than £20,000 must play at least three games for their temporary club before the Championship registration deadline in order to feature in any subsequent matches that season.
Hull FC’s Ben Crooks played for the Dons against Keighley last month, after the deadline, having only featured twice prior to the July 25 cut off date.
Hall – who presented the Dons’ case to the tribunal – insists it was admitted Crooks did feature in the game but disagrees with the decision.
He said: “Whilst we do not dispute Ben played in the game, based on communications and dialogue we have had with the RFL prior to the player participating in the game we are disappointed with the outcome of the hearing and the punishment that has been provided.
“We can confirm we will be appealing the decision.”
Championship rivals Batley were also deducted three points after fielding Jacob Fairbank against Sheffield.
