Carlos Ramos, the umpire at the heart of the astonishing controversy during the women's US Open final at Flushing Meadows on Saturday evening, returns to work today, as he sits in the high chair for the Davis Cup match between Croatia and the United States in Zadar.
Mr Knight, who has a reputation for controversial cartoons, was pilloried for his portrayal.
Knight responded to the criticism by pointing out that he had drawn an unflattering portrayal of Australian male tennis star Nick Kyrgios "behaving badly".
Or the post was too much for Twitter (it's not clear which.) As of Tuesday morning, Knight's Twitter account - where he was flooded with comments after proudly posting the cartoon on Monday - was no longer active.
While tennis legend Billy Jean King backed Williams" accusation insisting there was a "double standard', many have condemned the 23-time Grand Slam victor for losing her temper.
While tennis legend Martina Navratilova does believe Williams "completely had the right message about women's inequality", she partly agreed with Djokovic.
It is well known that Williams is one of Osaka's idols but she's now opened up on how she narrowly avoided bumping into another of her heroes at the US Open. "It had nothing to do with gender or race. this was about a bad sport being mocked".
First she was warned after her coach Patrick Mouratoglou was seen communicating with her via a hand gesture and then she was docked a point after smashing her racket.
That's a kind gesture from Williams, considering Osaka later admitted she thought the crowd was booing her because it wanted Williams to win instead. I drew her as she is, as an African-American woman.
William's loss cost her a chance to equal Margaret Court's record of 24 Grand Slam titles.
Karl continued, 'The moment we start trying to crack down on cartoonists is a slippery slope to a world that I just think is changed beyond recognition'.
