At the
2004 World Junior Championships in Athletics, Kimmons was part of a Gold medal winning
4×100 meters relay squad that established a
junior world record with 38.66 seconds. Kimmons attended
Hinds Community College, where he won three individual national championships (200m outdoor in 2005, 60m and 200m indoor in 2006) and set national championship indoor meet records at 60m and 200m. He committed to
Mississippi State University in November 2005, but chose to turn pro in March 2006. Kimmons finished fourth in the
60 meters at the 2010 IAAF World Indoor Championships with 6.59 seconds. At the
2010 USA Outdoor Track and Field Championships, he won a
silver medal behind
Walter Dix. At the 2010
Weltklasse Zürich meeting, he ran a new personal best of 9.95 seconds over 100 metres, becoming the 72nd person to break the
10-second barrier. At the
2012 Summer Olympics, Kimmons was part of the
4×100m relay team that broke Team USA's national record on route to winning the silver medal. However, on 13 May 2015, the
United States Olympic Committee announced that following the doping conviction of
Tyson Gay, the medal winning team of 2012 would all be stripped of their medals, meaning that Kimmons had to hand back the only Olympic medal he ever won in his career. Kimmons finished second at the 2014
USA Indoor Track and Field Championships in the 60 metres and thus qualified for the
2014 IAAF World Indoor Championships.
USADA banned Kimmons for two years, starting in April 2016, for consumption of a banned stimulant via a supplement. Also a
football player in high school, Kimmons caught 13
touchdown passes and made four
interceptions during his senior year. He was rated a two-star recruit by
Scout.com. ==References==
