The striker used his Twitter account to post a link to a  statement issued through a lawyer to set the record straight after the disappearance in July of the rapper Castro and girlfriend Janet Bandu.
The pair were on holiday with Gyan in the Ghanaian coastal town of Ada when they disappeared while using a jet ski, which was recovered without any trace of their bodies.
"Sadly, the expression of empathy during a person's moment of grief and utter dismay does not sell in the media," the statement said.
"What sells in the media, and what indeed sold and is still selling in the media in Ghana are wild allegations and rumours directed especially at Asamoah Gyan ranging from the absurd...and ending with the ludicrous -- that he sacrificed him spiritually to enhance his career."
The statement said Gyan, who plays for Al Ain in the United Arab Emirates after a stint at Premier League Sunderland, and family had previously kept their silence while police investigations were continuing.
"In our painful silence, we have been totally dismayed by the fact that the platform was provided for the peddling of these wild and ludicrous allegations and rumours against us," it added.
"Those to whom the platform was provided offered no evidence whatsoever to back their statements. And indeed, the allegation of spiritual sacrifice can by no stretch of the imagination be propped up,” it further said.
