VIDEO: Tiger Woods Admits Federal Investigators Have Contacted His Agent In Drug Probe

Tiger Woods admitted that federal investigators have contacted his agent regarding a drug probe. During his first full-fledged news conference Monday since his cheating scandal exploded last November, Tiger faced questions about Dr. Anthony Galea, a sports medicine specialist who has treated many athletes but was arrested in connection with dispensing performance-enhancing drugs.

Facing reporters in Augusta, Georgia, site of the 2010 Masters golf tournament, Woods again apologized for the cheating scandal, but was also asked about reports he has taken performance enhancing drugs and about meeting with Dr. Galea.

Woods denied ever taking illegal drugs, like HGH, and said Dr. Galea gave him only PRP treatment. PRP puts platelet enriched plasma into the body.

"He's worked with so many athletes,”  Woods said of Dr. Galea. “There's some comfort level to that when a person has worked with athletes."

Wood also said he received the plasma treatments following his knee surgery in 2008 when he blew out his ACL and he LCL was “not responding” to treatment. He also said he then tore his Achilles and kept re-tearing it and even sought treatment in a hyperbaric chamber.

But Dr. Galea, who lives in Canada, has been accused of treating patients with Human Growth Hormone and Actovegin, a drug extracted from calf’s blood. Using, selling or importing Actovegin is illegal in the United States.

Tiger denied taking either of those treatments.
