What happens when players swear at Wimbledon?
After British number one Heather Watson becomes the latest tennis star reprimanded over her on court language we ask - what happens to players who swear?
Many players down the years, some at the top of their game, have been caught out for their colourful use of language.
However this year at the All England Club players have managed to turn the air blue after just two days.
Five-time champion Serena Williams was given a code violation for an "audible obscenity" during her first round win against Russian Margarita Gasparyan on Number One court.
Australian star Nick Kyrgios appeared to say "dirty scum" during his straight sets victory after a fiery exchange with an umpire, although he claims he was talking to himself.
Briton Liam Broady was also given a court violation for swearing as he battled through a five-set thriller against Australian Marinko Matosevic.
So what happens, when in the heat of the moment a player says the wrong thing?
Players can be fined by up to $20,000 (over £12,700) for a code violation.
If a violation happens during the warm-up or in a match it usually initially results in just a warning.
However a second offence can lead to a one-point deduction.
A third instance can result in losing a game.
A fourth case can see a player potentially lose the match.
23-year-old Watson had a point docked after being slapped with a code violation for "audible obscenity".
