Rafael Nadal withdraws from Montreal tournament

Rafael Nadal pulled out of next week's National Bank Open in Montreal, citing "a little discomfort" as the cause.

An abdominal strain forced Nadal, ranked No. 3 in the world, to withdraw from the semifinals at Wimbledon, where the Spaniard was scheduled to meet Australian Nick Kyrgios.

At Wimbledon, Nadal was seeking his 23rd Grand Slam title -- third this year following his wins at the Australian Open and French Open.
