Fury's promoter, Mick Hennessy, has deemed the result of the fight as controversial, even suggesting corruption was evident in the judge's scoring, and has stated an appeal will be filed.
Duggan said only the British Boxing Board of Control has the power to overturn the decision, which seems unlikely.
The WBO could force Parker to partake in a rematch if the outcome is considered irregular, but whether that will come to fruition also appears unlikely.
