Novak Djokovic joins Andy Murray, Serena Williams in Miami withdrawal

Djokovic, who was knocked out at Indian Wells in the second round by Nick Kyrgios, had reportedly been struggling with an elbow injury.

In a tweet posted on Sunday evening the Serbian confirmed that he would not be participating.

He said in a longer statement on Facebook that it was the elbow injury and he has been advised not to play.

He said:

"I have some very disappointing news to share with you regarding the Miami Open tournament. My doctor has strongly advised against play because my elbow injury, that I keep carrying on for months, got worse in the past week.

"I will do everything in my power to recover and do all the necessary therapy to be able to return on court as soon as possible. Sadly, I won't be able to defend my title in Miami this week.

"Believe me, it is as shocking to me, as it is to you. I had incredible run in Miami, I won there my first masters tournament and started my campaign towards the top of the world rankings. No wonder they say that in sport the biggest and most painful defeats come from injuries, and not from opponents.

"I am lucky that throughout my career I didn't have many injuries, but I guess that all that I've been through physically in the past so many years did leave a mark on my body. I remain eternally grateful for all the love and support I receive from you. Thank you for believing in me #NoleFam."

He follows World number one Andy Murray, who also withdrew due to an elbow injury.

In the women's bracket Serena Williams has withdrawn.
