Twelve-time Olympic medallist Ryan Lochte has been given a 14-month ban for a doping violation.
The 33-year-old American has been sanctioned by the US Anti-Doping Agency for an intravenous infusion.
While Lochte was not using a banned substance, athletes cannot usually receive IVs unless related to a hospitalisation or via an exemption.
Lochte posted a photo of himself on social media receiving the IV which prompted an investigation.
In 2016, Lochte – the second most decorated US swimmer behind Michael Phelps – was banned from the sport for 10 months after falsely claiming he was robbed at gunpoint during the Rio Olympic Games.
His latest ban runs until July 2019 having been backdated to May 24, the date he received the prohibited intravenous infusion.
