Galea is accused of drug smuggling, conspiracy, lying to federal agents, unlawful distribution of human growth hormone and introducing an unapproved drug into interstate commerce in court papers filed Tuesday in Buffalo.
Moss is rehabilitating his left knee after minor surgery. He would not discuss the matter at Redskins Park on Wednesday.
"I'll talk about football. I don't know about nothing else," Moss told the newspaper. "I ain't got nothing to do with nothing that ain't about me."
Citing unidentified sources close to the case, The Buffalo News reported federal prosecutors do not intend to file criminal charges against Moss or any other athlete with connections to the doctor. That paper's report did not link Moss, 30, to the use of HGH.
Redskins senior vice president Tony Wyllie said, "This is an off-the-field matter. I'm going to refer all questions to his agent, Drew Rosenhaus."
An employee at Rosenhaus' office declined to comment when contacted by the Buffalo paper.
NFL spokesman Greg Aiello said Tuesday the league did not know the identities of any of the players listed in the criminal complaint filed Tuesday by the U.S. Attorney's Office.
HGH is among the banned substances in the NFL, though the league doesn't specifically test for it. Players are subject to punishment if they're known to be in violation of the league's drug policy.
"Officials of the NFL and other sports organizations can sleep soundly tonight, because there is nothing he did with these athletes to help them with performance enhancement," Buffalo lawyer Mark J. Mahoney said of Galea. "(He) strictly provided treatment for injuries. If any athlete got (HGH), it was injected directly into injured tissue, in very small amounts, for purposes of healing."
Galea has treated Tiger Woods, Alex Rodriguez and other high-profile athletes. A former doctor for the CFL's Toronto Argonauts, Galea is known for using a blood-spinning technique, platelet-rich plasma therapy, designed to speed recovery from injuries.
