American sprinter Ryan Bailey has  been  hit  with  a  back-dated  six  months  ban  which  ended  last  month.

The 2012 Olympic sprinter and believed-to-be 2018 Olympic bobsled hopeful received the ban last week.

Bailey, who was fourth in the 2012 Olympic 100 metres in London, tested positive for a banned stimulant on January 10 at a bobsled race.

He said the failed test was caused by taking a high-risk dietary supplement that did contain a banned stimulant, but not the one for which he tested positive.

The standard ban for Bailey’s infraction is two years, but it was reduced following a July 25 hearing “based on his light degree of fault.”

Bailey was provisionally suspended on January 29, but the six-month ban was backdated to his January 10 test date and thus ended July 9.

The arbitration decision was signed July 26………….the following day, bailey competed at the USA bobsled national push championships, tying for 19th out of 26 men.
