Rafael Nadal's debut at the Madrid Open has been pushed back a day because of an ear infection.

Organizers say Nadal was examined by his doctors and it was agreed that he could compete in Spain's capital after 24 hours.

The four-time champion says the infection "is nothing important" but is a "little bit painful."

Nadal will play his second-round match against Fabio Fognini of Italy. Nadal had a bye in the first round.

This year, the fifth-ranked player in the world  has won two consecutive titles on clay, the Monte Carlo Masters and the Barcelona Open.

Nadal's last title in Madrid was won in 2014.
