Abdi Abdirahman, the Somalian emigre and four-time Olympian who is known as “The Black Cactus,” withdrew on Wednesday from the 117th Boston Marathon with the flu. With the 34-year-old Abdirahman absent, the entire US men’s squad from last year’s London Games will be missing from Monday’s race. Ryan Hall, who set the American record here two years ago, pulled out last month after a quadriceps strain hampered his training. Then Athens medalist Meb Keflezighi opted out last week after a nagging calf injury shortened his preparation.
Abdirahman, who competed in three Games in the 10,000 meters on the track, dropped out of last year’s Olympic marathon with a knee injury.
With the Olympians out of the field Jason Hartmann, who placed fourth last year, will be the top hope to end a three-decade domestic drought in Boston, where no American has won since Greg Meyer in 1983.
