James Stewart: Head
James crashed in his heat race last week and was run into by a few other riders (who had nowhere to go). He looked to have hurt his leg, but everything turned out fine except his head, where he took a good bump. As on Thursday the team was not sure if he was racing, but Friday morning it was announced he is out for Toronto.
JS7 will be sitting out for Toronto.
