Just four days before the 2012 Boston Marathon, Kenya's Robert Kiprono Cheruiyot, who set a course record with his win two years ago, has withdrawn from Monday's race with an "unspecified injury."
Cheruiyot, the 2010 champion, was the first runner to break the 2:06 mark in the Boston Marathon when he won the race with a then-record time of 2:05:52 -- It broke the course record by more than a minute. That record would only last for a year, however, as fellow Kenyan Geoffrey Mutai shattered the mark with his win in 2011, breaking the tape in just 2:03:02.
Cheruiyot came in sixth place last year (2:06:43). The 23-year-old also finished sixth at the 2010 Chicago Marathon.
Additionally, Russia's Galina Bogomolova and Ethiopia's Mamitu Daska have both scratched from the women's event.
The 2012 Boston Marathon, the 116th running of the famous race, takes place Monday, April 16. The elite men start at 10 a.m. ET.
