Dr. Anthony Galea, who has also treated Olympic swimmer Dara Torres and NFL players, was found with Actovegin and human growth hormone at the U.S.-Canada border last September.
It's illegal to use, sell or import Actovegin in the U.S.
The Times reported Galea visited Woods at his home four times in February and March for post-surgery treatment.
Galea also told the newspaper that "it would be impossible" for investigators to have found anything linking his athletes to performance-enhancing drugs and denied any wrongdoing.
Mark Steinberg, Woods agent, apparently asked that this article take an indefinite leave of absence from print, saying, "I would really ask that you guys don't write this? If Tiger is NOT implicated, and won't be, let's please give the kid a break."
