FORT LAUDERDALE, Fla. — Ryan Lochte posted a photo for the world to see, and the U.S. Anti-Doping Agency noticed.

It got him suspended — again.

The longtime U.S. swimming star has been banned from competition until July 2019, which means the 12-time Olympic medalist cannot compete as planned in the national championships that start this week in California. Lochte will also be ineligible for other top meets, including the Pan Pacific Championships later this year and next year’s world championships.

Lochte’s offense was that he got an intravenous injection in May — a method typically banned under anti-doping rules. The 14-month ban, retroactive to May 24 and announced Monday by USADA, is his second in less than two years following his 10-month suspension for his behavior during a drunken incident that created widespread scorn at the 2016 Olympics.

U.S. anti-doping officials said Lochte, who was holding a news conference Monday in South Florida to discuss the matter, was not taking a banned substance.

In Brazil, there were questions about his version of what happened.

This time, he revealed what happened.

Lochte’s violation essentially came to light when he posted the photo of him getting the IV on his social media accounts. That triggered the USADA investigation, one that Lochte “fully cooperated” with according to U.S. officials.

“Lochte received an intravenous infusion of permitted substances at an infusion clinic,” the USADA announcement of the suspension said. Under most circumstances, athletes cannot receive IVs unless related to a hospitalization or when allowed under the terms of a USADA-approved exemption — and Lochte fell into neither category.
