After missing 320 days following a pair of hard hits to the head last winter, Sidney Crosby is all too familiar with the term “precaution.”

But with their 24-year-old captain back on the ice and displaying the production that made him the face of the NHL, the Penguins would rather be overly cautious than risk losing Crosby again.

According to the team’s Web site, Sidney Crosby did not accompany Pittsburgh on its road trip to Philadelphia for Thursday’s game and will also miss the team’s Saturday date at the New York Islanders as a precaution.

“Sidney took a hard hit during our game against Boston Monday night and wasn’t feeling 100 percent,” general manager Ray Shero said. “He saw Dr. Micky Collins of UPMC today and took an ImPACT test, which showed no problems. However, we all think it’s best that he sits out the next two games as a precaution.”

Crosby has already piled up 12 points in eight games since returning to the lineup for the top team in the Eastern Conference.
