Juan Martin Del Potro will miss this week's Madrid Masters after a viral infection forced him to withdraw from the 2013 Mutua Madrid Open.
Del Potro, who missed this week's Portugal Open, has confirmed he has been unable to recover in time for the Masters 1000 series event in the Spanish capital.
Delpo will likely be extremely disappointed to miss out on the event. He reached the semi-finals last season, where two lost tie-breakers saw him fall to eventual runner-up Tomas Berdych on the blue clay.
As a result of his withdrawal, Del Potro will lose 360 ranking points, which is more than you'd receive for winning many ATP events.
Although Del Potro isn't necessarily a natural dirtballer, there's every reason to believe that he could have done well in Madrid next week. He reached the semi-finals back in 2009 too, when the tournament was played on the more familiar red clay, and made a bright start in 2010 before having to retire ahead of a third round meeting with Rafael Nadal.
With Del Potro out of the draw, Belgium's David Goffin will step in. The 22-year-old has never competed in the Madrid main draw, though he reached round four at the French Open as a qualifier, taking a set from Roger Federer before bowing out in a four-setter.
