Cornish Pirates have lost an appeal against their points deduction for breaching injury replacement laws.
An independent panel upheld the decision by the Rugby Football Union, docking the Pirates of a match-winning try from fly-half Bertie Hopkin against Bedford in the British & Irish Cup.
Hopkin came on for injured prop Tyler Gendell after two front-rowers had already been replaced.
But they should have played with 14 men, with uncontested scrums required.
The ruling means that the Penzance-based club have won only one of their opening three group games in the cup so far this season.
