Novak Djokovic has withdrawn from the Miami Open with a right shoulder injury, organisers said on Sunday.
The 24-time Grand Slam champion reached the fourth round at Indian Wells this week, but the six-time Miami champion opted out of the second leg of the "Sunshine Double" – where he fell to Jakub Mensik in last year's final.
Indian Wells marked 38-year-old Djokovic's first tournament since he lost to Carlos Alcaraz in the Australian Open final.
He played with a compression sleeve on his right arm, telling Tennis Channel he was dealing with a forearm injury that was intermittently affecting his serve.
"If I don't serve for five or six minutes, then I feel like the first couple of serves of that game are a bit painful," Djokovic said.
