The alleged incident took place at the Hammers' training ground on 6 February.

The 31-year-old Scotland international, who faces a one-match ban and an £8,000 fine, has until 18 March to respond to the charge.

BBC Sport understands Snodgrass was not scheduled to be tested, nor did he refuse to take a test.

"Robert Snodgrass has been charged with a breach of FA Rule E3(1)," the FA said in a statement on Monday.

"It is alleged the player used abusive and/or insulting words towards UK anti-doping officials who were visiting West Ham United's training ground on 6 February 2019 to conduct out-of-competition testing."

Snodgrass has played 32 times for West Ham this season, scoring four goals in all competitions.
