Andy Murray accused second-round rival Fernando Verdasco of breaking the rules during a heat break at the US Open.
Murray, who lost the match 7-5 2-6 6-4 6-4, reported the Spaniard – claiming he spoke to his coach during the heat break in their US Open second-round tie.
Verdasco has denied the allegations, causing Murray to joke on social media: "I'm off to get a health check as apparently I've started imagining things."
"When I came out of the shower, his coach and one of the Spanish doubles players were in there chatting to him, and you're not allowed to speak to your coach," said Murray.
"I'm not blaming Fernando and his team. They certainly weren't trying to break any rules.
"It shouldn't be for the player that's competing against him to have to go to the supervisor."
