MADRID, Oct. 9 (Xinhua) -- World number two Roger Federer will play at next week's Madrid Masters, organizers said on Thursday.
Federer won the Madrid Masters in 2006 and was a finalist in 2007 in the event, which this year begins on Saturday with qualification matches and ends on October 19.
The Swiss had a layoff of two weeks as he skipped this week's Stockholm Open.
The tournament could pit Federer against Rafael Nadal for the first time since the Spaniard assumed the No. 1 ranking, which the Swiss star had held for a record 237 weeks.
Federer was knocked out of the Olympic tournament in Beijing before a potential matchup with Nadal, who won the gold medal.
The pair haven't met since Nadal ended Federer's bid for a sixth straight Wimbledon crown in June.
