George Hincapie, a teammate of Lance Armstrong on the U.S. Postal Service cycling team, released a statement Wednesday admitting to doping, reports Bicycling.com.

"Three years ago, I was approached by US Federal investigators, and more recently by USADA, and asked to tell of my personal experience in these matters," Hincapie's statement said. "I would have been much more comfortable talking only about myself, but understood that I was obligated to tell the truth about everything I knew. So that is what I did."

Hincapie joins the list of Armstrong teammates that have admitted to using performance enhancing drugs. The list includes Floyd Landis, Tyler Hamilton, Frankie Andreu, and Jonathan Vaughters. Armstrong has not responded to Hincapie’s statement. The U.S. Anti-Doping Agency said it will release 1,000-plus pages of Lance Armstrong doping file later Wednesday.

Along the way, Hincapie raced alongside Armstrong as a key teammate during all seven of the Texan’s Tour de France victories. Hincapie’s history with Armstrong dates to 1994, when Hincapie joined the Motorola team that Armstrong already rode for. But it was on U.S. Postal Service in 1999, Armstrong's first Tour win, where the two became inseparable.
