Report: Crosby battles injury

Sidney Crosby, the Pittsburgh Penguins' leading scorer, missed Saturday's game against the Chicago Blackhawks with a nagging groin injury, according to a Pittsburgh Post-Gazette report.

Crosby left the Penguins' morning skate after spending five minutes on the ice Saturday morning.

The paper is also reporting that the Penguins have recalled forward Mark Letestu from the team's Wilkes-Barre/Scranton affiliate to replace Crosby. The 24-year-old Letestu made his debut with the Penguins earlier this season.

The Penguins (20-9-0), the defending Stanley Cup champions, sit atop the Atlantic Division, and take on the Central Division-leading Blackhawks at Mellon Arena Saturday night at 7:30 p.m. ET.

Blackhawks coach Joel Quenneville told ESPNChicago.com's Jesse Rogers that he and the team are looking at the Pittsburgh game as a measuring stick.

"I'm looking for a response from tonight's game as opposed to the opposition tomorrow," Quenneville said after the Blackhawks' 4-1 loss to the Predators on Friday. "We know we are going to get tested."
