This is not the first time Sandgren has been in the news for his controversial views. In 2018, as his tennis career was taking off, fans found alt-right messages on his social media account. But he quickly deleted messages from his social media feed to avoid controversy.
Tennys Sandgren has been active on Twitter expressing his support for Djokovic.
He also got hundreds of new followers from Serbia.
John Isner is another player who has not been afraid to voice his opinion. Isner feels that Djokovic followed the rules and that his detention is a disgrace.
