RAFAEL Nadal could play at Hurlingham this Friday as he prepares to defend his Wimbledon title next week.

The World number one is recovering from a knee injury which kept him out of Queen's last week.

But the Spainard, who played at the Wimbledon warm-up in 2006 and 2007, could return against Switzerland's Stanislas Wawrinka in the Fortis Tennis Classic in three days time.

He said: "I have kindly been invited to play the traditional exhibition at Hurlingham.

"It would be a good test for me to play there to see how the knee is doing, and it would provide the perfect setting to get some practice before Wimbledon.

"If I feel the recuperation is going well I will be more than happy to be there again. I hope that's the case,"

Other ATP Tour players include Marat Safin, James Blake and Tomas Berdych, who will compete at this event in a series of daily exhibition matches.

The event will also see the debut of former British number one Greg Rusedski, who will be joined by Pat Cash, Henri Leconte, Mats Wilander and Mansour Bahrami in the doubles competition.
