Sportswear giant Nike has abandoned its contract with disgraced cycling champion Lance Armstrong in the face of mounting evidence he was involved in doping.
Two other sponsors, beer firm Anheuser-Busch and sportswear firm Oakley, have also said they are looking towards not renewing contracts with the man who once dominated the Tour de France.
Nike cited "seemingly insurmountable evidence that Lance Armstrong participated in doping" as the fallout from last week’s U.S. Anti-Doping Agency report continues.
Anheuser-Busch will not renew its contract with Armstrong at end of 2012, but will continue to support his foundation Livestrong.
He resigned as chairman of Livestrong - the organisation raised almost $500 million to help people affected by cancer.
Sportswear firm Oakley told the BBC: " We are reviewing the extensive report from the Usada, as well as our relationship with Lance, and will await final decision-making by the International Cycling Union."
