Rafael Nadal pulled out of next week's hard-court tournament at Rotterdam, Netherlands, because of the bad back that bothered him during the Australian Open.
Nadal's withdrawal from the ABN AMRO World Tennis Tournament was announced Thursday.
The 20-time Grand Slam champion wrote in a series of posts on Twitter that he “found a temporary solution that allowed me to play without pain in the second week” of the Australian Open, where he lost in the quarterfinals to Stefanos Tsitsipas in five sets.
But, one of Nadal's tweets said, “Once I got back to Spain I visited my doctor and together with my team they’ve advised not to play this upcoming week. I was really looking forward to coming back to Rotterdam and The Netherlands since it’s been a while (since) I played there.”
The second-ranked Nadal would have been seeded No. 1 in Rotterdam. Instead, third-ranked Daniil Medvedev, the runner-up to Novak Djokovic at the Australian Open, will take the top spot in the seedings.
If Medvedev reaches the final in Rotterdam, he would replace Nadal at No. 2 in the rankings, according to the ATP Tour. That would allow Medvedev to become the first man other than Nadal, Djokovic, Roger Federer or Andy Murray to be in the ATP's Top 2 since Lleyton Hewitt was second to Federer in July 2005.
Nadal cited the back issue when he sat out the ATP Cup team competition at Melbourne Park that preceded the Australian Open.
The 34-year-old Spaniard then was able to participate in the year's first Grand Slam tournament, which began Feb. 8.
