According to this cyclingnews story the UCI is going to inform teams of suspicious results next week and leave it up to them whether to take action.
"The riders will be informed early next week," said UCI president Pat McQuaid, according to AFP. "We will inform their teams and national federations. We will [then] name the riders and will start disciplinary proceedings against them."
McQuaid did not reveal the names of the riders involved nor the teams effected. Sources within the UCI have indicated that the names of riders could emerge on Monday of next week.
McQuaid went on to explain that the UCI would not itself be suspending the named riders, instead leaving it to teams to decide what action should be taken immediately against their riders. "There will be no provisional suspension. It will be up to the teams to decide what they do," said McQuaid.
So 'disciplinary action' is actually going to be limited to letting the teams decide what to do? Needless to say, those three paragraphs don't entirely sit well with one another.
Edited to to add: Jens actually beat me to posting this here. Discussion ensued. Leaving this up because it's probably worth discussing under its own heading rather than in a race thread.
It gets worse: majope also beat me. And more discussion. I didn't read the race thread, silly me.
