He was one of the most famous men in sporting history, but on this day in 2012 cyclist Lance Armstrong's fall from grace was clear, as Nike cut all ties with him after he was revealed as a drugs cheat.
Rumours had swirled for years that Armstrong had cheated his way to his seven Tour de France titles while he was lead cyclist with his US Postal Service and Discovery Channel teams.
In October 2012 an extensive report by the US Anti-Doping Agency (Usada) eventually found that the athlete was part of "the most sophisticated, professionalised and successful doping programme that sport has ever seen".
Armstrong strongly denied the allegations but said the process of fighting the Usada report was unfair.
But the report proved impossible to dismiss, forcing Armstrong to stand down as chairman of the cancer charity he had founded, Livestrong, and then on 17 October being told that Nike was severing its connections with him.

The company had initially suggested it would stand by the cyclist, but said in a statement on 17 October, 2012 that it had been misled by Armstrong.
The statement said: "Due to the seemingly insurmountable evidence that Lance Armstrong participated in doping and misled Nike for more than a decade, it is with great sadness that we have terminated our contract with him. Nike does not condone the use of illegal performance enhancing drugs in any manner."
The company said it planned to continue to support Livestrong - a move made possible by the fact Armstrong had stood down.
Armstrong finally admitted publicly that he had cheated to win all seven of his Tour de France titles in a tell-all interview with Oprah Winfrey in January 2013.
During the interview, Armstrong said it would not have been possible to win the titles without cheating, such was the prevalence of performance-enhancing drugs in the sport at the time.
But he denied threatening other team-mates to do the same, and denied taking drugs during his comeback in 2009 and 2010.
Regardless of his apology, the scandal has continued to dog Armstrong and affected what would have been an astonishing legacy.
As a cancer survivor, having to walk away from the charity he formed was undoubtedly difficult.
Armstrong was also stripped of his seven consecutive Tour de France titles from 1999 to 2005 after the investigation and his own admissions.
The financial impact also continues nearly a decade after his sponsors walked away from him, with Armstrong settling a civil lawsuit with the US Department of Justice in April 2018 and agreeing to pay $5 million to the US government following whistleblower proceedings brought by former team member Floyd Landis.
