American tennis player Wayne Odesnik has been given a 15-year ban for a second doping violation.
The 29-year-old was handed a one-year suspension back in 2010 after admitting to importing human growth hormone from Australia.
Odesnik's latest offence saw him fail two out-of-competition tests in December 2014 and January 2015.
"Mr Odesnik's commission of an Anti-Doping Rule Violation under Article 2.1 of the Programme was confirmed, which was his second such violation, having been sanctioned in 2010 for the possession of human growth hormone," read a joint statement from the Tennis Anti-Doping Programme and the United States Anti-Doping Agency.
"It was, therefore, determined that he is suspended from participation for a period of 15 years, back-dated to commence from 30 January 2015, and so ending at midnight on 29 January 2030.
"It was also determined that Mr Odesnik's results at the Happy Valley Challenger event, Australian Open and Maui Challenger event should be disqualified, with forfeiture of the ranking points and prize money that he won at those events."
Odesnik's best appearance at a Grand Slam was when he reached the Australian Open third round back in 2008.
