Weigh down injuries to Paul Pierce, Kobe Bryant and Stephen Curry

Paul Pierce (Celtics), Kobe Bryant (Lakers) and Stephen Curry (Warriors) will be out injured for the next preseason game . They could even miss the start of the regular season.

A severe contusion on the heel during the first full training at Boston has left the star KO. "Yes, I'm worried about Pierce's injury. We want to rest," said Doc Rivers, coach of Massachusetts at ESPN.com . It's completely ruled out its participation in the preseason game against Toronto on Wednesday.

Kobe Bryant, meanwhile, became a sprained right wrist during a set with DeAndre Jordan in the match that the Lakers lost to the Clippers 95-114. Nor will, almost certainly, in the second assault on California neighbors, reports LA Times .

The Golden State player Stephen Curry sprained his ankle against the Kings and it seems unlikely that force recovery for the second pre-season friendly.
