URGENT ¥¥¥ Tennis: Nadal out of Brazil Open doubles over knee fear

Rafael Nadal will not play his scheduled doubles match at the Brazil Open Wednesday because of "knee overuse", organizers said.

But they added that the Spanish star intends to play his opening singles match later Thursday against Brazilian Joao Souza.

World number five Nadal had been scheduled to team up with Argentina's David Nalbandian in a second-round encounter against Argentine Horacio Zeballos and Austrian Oliver Marach on Wednesday.

Former world number one Nadal only returned to the tour in Chile last week after a seven-month injury absence.
