MADRID — Rafael Nadal is training for the first time since being sidelined by a knee injury.

Nadal has been out of action with tendinitis in his right knee since losing to Robin Soderling in the fourth round of the French Open, where the Spaniard had been the four-time defending champion.
Nadal is hoping to resume playing at next month’s Montreal Masters. He was was unable to defend his Wimbledon title, and Roger Federer won his record 15th Grand Slam trophy and retook the No. 1 ranking.
Nadal is returning from a leg problem for the third time since October.
