Maybe those tight pants that cycling racers wear are so constricting that it affects the flow of blood to their brains.

A few days ago, we told you about German cyclist Patrick Sinkewitz's bizarre accident at the Tour de France, where he ran into a spectator after the day's competition ended while Sinkewitz was headed to his hotel. The spectator was hurt seriously and the rider suffered a broken nose.

Now, it seems, that Sinkewitz also failed a drug test a month before the Tour. Here's another interesting development. Two German public broadcasters have suspended their coverage of the Tour pending results from Sinkewitz's B sample. Fed up with the cycling scandals, especially involving Germans, the broadcasters are saying that without a clean race, the Tour de France isn't worth covering.
