The U.S. record holder, suspended after a 2013 positive test for
an anabolic steroid, will race American rival Justin Gatlin, who
served a four-year doping ban, and Frenchman Jimmy Vicaut over 100
meters at the July 3 meeting.
"Lausanne has always been one of my favorite meets, and I'm thrilled
to have it be my opening meet," said Gay, noting he had been in
training for several months.
The U.S. Anti-Doping Agency (USADA) said last month that Gay, the
world's joint second fastest man, had accepted a one-year suspension
backdated to June 23, 2013 after offering what it termed substantial
assistance in his case.
He also returned his silver medal from the 4x100 meters relay at the
2012 London Olympics.
The controversial decision meant Gay would be eligible to compete
from June 23.
Normally athletes receive a two-year suspension for their first
doping offence but under anti-doping rules the ban can be reduced
for substantial cooperation.
