Kirk Flinte who works for a cycling company tweeted that Tyler may have tested positive at the Tour of California. The ramifications of the US Road Champ testing positive? I can't even begin to imagine. Yikes.

Edited: Kirk Flinte deleted all tweets related to the issue at approximately 12:55pm today. The original tweet read, "Tyler Hamilton positive at ToC?"

If this turns out to be false all I can say is wow. What would motivate some one to start a rumor like that?

Chris here -- We are not a source for this rumor. As ZoeRochelle makes clear, she was simply reporting on the fact that a person connected to the sport was twittering about a possible rumor. Make of it what you will, but this story is pretty close to baseless, and I think rumors like this are too explosive to go on unchecked. I will leave this fan post up because ZoeRochelle has done a good job clarifying and updating, and because the discussion below is a good example of how people should treat unfounded rumors.
