WATCH: Troicki, Tomic ordered off court by D.C. cop

Bernard Tomic and Viktor Troicki were ordered off a practice court by a policeman in Washington, D.C., a video clip online showed.

The police warning was because of severe weather in the area. The policeman walks into the middle of the court mid-rally to tell them to "get off the court."

Troicki protests, waving his arms toward the non-raining sky, prompting the police officer to demand more directly that they leave. "Do you want to knock it off now? Knock it off," he says. "Leave, come on. Let's go."

Tomic approaches and points out, “Excuse me, sir, but it's not raining."

The two players, who are known for their occasional verbal displays on court, oblige eventually and gather their equipment to leave the court.

Tomic is set to face Ivo Karlovic in the third round, while Troicki fell in the second round to Ryan Harrison.
