After suffering a knee injury in competition last week, Miami Heat forward Kelly Olynyk will be unable to compete for Canada in the FIBA World Cup, a source tells ESPN's Adrian Wojnarowski.

Olynyk is expected to be ready for the start of the NBA season.

Olynyk slipped and fell during the third quarter of Canada's win over Nigeria in a FIBA exhibition game on Wednesday. X-rays were negative, and the plan was for Olynyk to sit out a week, including an exhibition game on Friday in Winnipeg.

On Thursday, Canada coach Nick Nurse had said he expected Olynyk to play in the World Cup.
