(CNN) -- Rafael Nadal is on the comeback trail after an injury-blighted summer which has seen him lose his French Open and Wimbledon crowns as well as the world number one spot to arch-rival Roger Federer.
Nadal crashed out of the French Open in the fourth round and has not played since.
The 23-year-old Spaniard was struck down by tendinitis in both his knees and clearly struggling with the injury lost in the fourth round at Roland Garros to Robin Soderling of Sweden.
He then pulled out of his defense of the Wimbledon title he won in such thrilling fashion in a five-set epic with Federer in 2008.
Federer, who won both the grand slams, recaptured the world number one ranking from Nadal as he claimed a record 15th grand slam at the All England Club.
Nadal told his official Web site www.rafaelnadal.com that he would resume training on Monday and return to tournament action in the Montreal Masters which starts on August 8.
"I am really looking forward to practice again and to do what I most like: to play tennis," he said.
"The event in Montreal is important and I expect to be there and fit to play. Until then I need to continue to work on my recovery and practice well."
Nadal was also forced to miss his country's Davis Cup quarterfinal win over Germany last weekend.
"The evolution of his injury is positive and the player will continue with his physiotherapy and muscular work and will resume his tennis activity in a progressive way starting next Monday, estimating his return to competition on August 8th at Montreal," his doctor Angel Ruiz-Cotorro was quoted on the Web site.
