Rafael Nadal pulled out of the Miami Open on Tuesday because of the bad back that bothered him during the Australian Open.
The hard-court tournament begins next Tuesday.
“For the moment I need to fully recover from my back problem and start to get ready for the upcoming clay court season in Europe,” Nadal said in a statement.
The 20-time Grand Slam champion earlier withdrew from this month's tournament at Rotterdam, Netherlands. At the Australian Open, he lost in the quarterfinals to Stefanos Tsitsipas.
