FINA, the international governing body for swimming, has written to the US Masters Swimming to advise them to reject Lance Armstrong's entry to take part in a competition scheduled this weekend.
The disgraced cyclist was planning to use the small low-profile event in Austin, Texas, to make a return to competitive sport.
The competition falls under the jurisdiction of the US Masters Swimming. In a statement, the governing body said:
FINA wrote a letter to the US Masters Swimming (with copy to US Aquatic Sports and USA Swimming) requesting not to accept the entry of Mr. Lance Armstrong in the [...] competition.
