The New York Times first reported Maggette was the Duke basketball player who Watson's attorney accused of raping Watson during her sophomore year at Duke.
Maggette, who went on to play 14 seasons in the NBA and is now a freelance basketball analyst on Fox Sports West, denied the allegation in a statement to the Times
"It has only been through media accounts and a statement from Meredith Watson's lawyer that I first learned or heard of anything about the sexual assault allegation, "Maggette said, according to the Times. "I have never sexually assaulted anyone in my life and I completely and categorically deny any such charge."
CNN has been unable to reach Maggette independently for comment.
When contacted by CNN, Fox Sports West said it takes allegations of misconduct seriously.
"We are looking into the matter. We have no further comment at this time," the network said.
Watson's attorney, Nancy Erika Smith, said in a statement on Friday that after Watson was raped she went to an unnamed dean "who provided no help and discouraged her from pursuing the claim further." Watson also told Fairfax, Smith said.
Michael Schoenfeld, vice president of public affairs and government relations for Duke, said in a statement, "We are in the process of gathering information to determine what policies and procedures were in place during the "
Smith says Fairfax has used his knowledge of that assault allegation to take advantage of Watson.
When Watson asked Fairfax why she did it , Smith says he responded: "I knew that because of what happened to you last year, you'd be too afraid to say anything."
"Mr. Fairfax actually used the prior rape of his 'friend' against her when she chose to rape her in a premeditated way," Smith said.
"I say again without reservation: I did not sexually assault or rape Meredith Watson, Vanessa Tyson or anyone else," said Fairfax in the statement.
"The one thing I want to make abundantly clear is that in both situations I knew at the time, and I know today, that the interactions were consensual."
Fairfax said what he has "expressed is the truth."
"I would like to stand here in that truth and reiterate that my truth, as well as the truth of Dr. Tyson and Mrs Watson, should be fully investigated and thoroughly assessed," said Fairfax's statement. He called on the FBI to "investigate fully and thoroughly the allegations against me."
