Madrid: Rafael Nadal has cancelled an exhibition match against Novak Djokovic because of knee trouble.
He said doctors have told him to rest for 15 days because of tendinitis, so as to be ready for the London Olympics.
He and Djokovic were scheduled to play on July 14 for charity at Santiago Bernabeu Stadium, the home to Real Madrid.
"I will now work on my rehab as well as taking some short holidays to resume my practice in 15 days," Nadal said in a statement.
