From Todays runners world:
McGregor of Team USA Minnesota, who's been a USA 10,000-meter champion, and Wichita-based Osburn had both gotten the necessary inoculations but made recent decisions to bypass the World Cross Country Championships in Kenya. And Aurora Scott has withdrawn from the junior team. There have been no official announcements, but we hear even more athletes on the announced roster have decided against making the trip to Mombasa. Team USA Minnesota confirmed Tuesday, however, that two of its men, Andrew Carlson and Matt Gabrielson, will still be going.
