"Complete lunacy he can't compete" - John Isner on Djokovic at the US Open

As of now, Novak Djokovic can't compete at the US Open and John Isner thinks it's complete lunacy.

There are many people who are not fans of Djokovic not being able to play at the US Open and John Isner is one of them. The American always held outspoken views about and even now he's not afraid to admit that Djokovic not being in New York is absurd.

After a user wrote on Twitter about whether any American tennis players are urging for Djokovic to be allowed to play at the US Open, Isner responded by writing:

"Yes. Completely lunacy he can't compete as of now"

He tagged the post with a mocking hashtag #science which rubbed plenty of people in the comments the wrong way. It's obvious many are trying to get Djokovic into America for the US Open but for now, the US government is not showing any signs of willingness to do it.
