Serena Williams pulls out of Rogers Cup in Montreal with shoulder injury


World number one Serena Williams has withdrawn from next week's Rogers Cup in
Montreal because of an injury.

The two-time champion has not played since winning her seventh Wimbledon
title and has pulled out with inflammation in her shoulder.

Title holder Andy Murray, Roger Federer and Rafael Nadal have already pulled
out of the men's event in Toronto.

Williams, 34, will defend her singles and doubles titles when the Olympic
tennis event begins in Rio on 6 August.

"Of course, we are disappointed that Serena will not play in the tournament
this year," said Toronto tournament director Eugenie Lapierre.

"Because this is an Olympic year, the players have very full schedules.
Sometimes your body needs rest. We hope that Serena will recover quickly and
wish her much success for the rest of the season."
