"When healthy, the Penguins are considered among the NHL's finest teams.

But whether good health ever blesses the Penguins again is becoming a legitimate question.

Center Jordan Staal missed Saturday's game against the New York Islanders with what the team called a "lower-body injury."

Coach Dan Bylsma said Staal was injured in Philadelphia and is "day to day."

The injury is not believed to be serious."
