Chris Bosh is expected to miss the start of the Toronto Raptors' training camp because of a strained left hamstring.

The team made the announcement Friday.

The four-time all-star first felt soreness during a training session at home in Dallas last week. The pain returned during a workout in Toronto on Wednesday.

The Raptors open their five-day training camp Tuesday in Ottawa. They begin exhibition play Oct. 6 against the Philadelphia 76ers.

Bosh averaged a career-high 22.7 points and 10.0 rebounds a game last year. The six-year veteran will be a free agent at the end of the season.

He will be re-evaluated when the team returns to Toronto after the camp.
