There is a rumor that Ullrich may return to the peloton now that Operation peurto has been closed by a Spanish judge. This all depends on wether the judge releases the documents and blood bags to the UCI. If the judge does not turn over the evidence then the riders implicated will be exonerated completely from further scrutiny. This means that Ullrich will be free to get his racing license and sign with a pro tour team.
We may know more this week.
