Nadal withdraws from Buenos Aires with stomach virus
World No. 1 Rafael Nadal has withdrawn from next week's clay-court tournament in Buenos Aires, citing a stomach virus, which will prevent him from practicing the next few days. Nadal suffered a back injury during the Australian Open final, but said that injury is healing.
The 13-time Grand Slam champion is scheduled to play the Rio Open in Rio de Janeiro, Brazil, February 17-23.
