Edwards began his career as a junior athlete in 2000, winning the USA Junior and Junior College (JUCO) championships in the 100 and
200 meters races. Edwards competed for
Bevill State Community College and
Kansas City Kansas Community College in the
NJCAA. He competed at the
2000 World Junior Championships in Athletics and reached the semifinals of the 100 m and quarterfinals of the 200 m. He reached the final of the USA Outdoor Championships in Track and Field in 2003, setting a personal record of 10.09 seconds. He competed at the US Olympic trials for the
2004 Athens Olympics, but did not progress beyond the quarterfinals. He received a public warning that year from the
United States Anti-Doping Agency after he tested positive for
tetrahydrocannabinol, a compound found in marijuana, which is regarded as a minor infraction. At the 2005 US Outdoor Championships, he posted a personal record tying 10.09 s before finishing sixth in the 100 m final. As a result, he was selected as an alternate for the United States
relay team at the
2005 World Championships in Athletics, but he did not compete. At the end of the 2005 season, he ran a new personal best of 10.08 seconds in
Malmö, Sweden. The 2006 and 2007 seasons were largely uneventful, although he was part of the bronze-medal winning relay team at the
2007 Pan American Games. Edwards returned in 2008 to compete at the US Olympic trials for the
Beijing Games. He finished tenth in the semifinals but recorded a new best of 10.06 seconds in the qualifying rounds. At the start of the following outdoor season, he significantly improved his 200 m best from 20.46 to 20.17 seconds at the
Grande Premio Brasil Caixa de Atletismo. The following month, he improved his 100 m record to 10.02 seconds at the
Fanny Blankers-Koen Games in
Hengelo, finishing second behind
Churandy Martina. Edwards finished third in the national championships with a
wind-aided run of 10.00 seconds, gaining qualification into his first ever major senior championships, the
2009 World Championships in Athletics, along with
Mike Rodgers and
Darvis Patton. In August 2025, Edwards stated he is a serving a
USADA provisional suspension for giving
Marvin Bracy the phone number for a doctor that provides
performance enhancing drugs. USADA and USATF have not publicly verified the suspension. Edwards alleges there is a large drug-dealing network among United States sprinters. ==Personal bests==
