A quick Google search took me here, where "playing an unregistered player" seems to be the offence. 25 points for that seems rather harsh, perhaps there were aggravating circumstances.
Oak were deducted 25 due to playing a player still on loan to Birmingham Moseley as the loan agreement closure did not get processed but the coaches were not aware so played the player. We both GMS officials with the Vikings this went unnoticed.
