The Penguins have won three straight after Sidney Crosby scored his 31st goal and Marc-Andre Fleury recorded his fifth shutout Tuesday, but they received some bad news Friday when James Neal was diagnosed with a concussion.
Coach Dan Bylsma isn't sure when Neal, second on the team to Crosby and Chris Kunitz with 22 goals, will be back in the lineup.
"You don't know if you're talking about 1-2 days or much longer," Bylsma said. "You hope the symptoms subside and it's shorter (rather) than longer."
Kunitz also sat out practice Friday after crashing into the goal post in the third period against Washington. Bylsma said Kunitz has "bumps and bruises," and that his status for this contest is unclear.
Though Pittsburgh has earned at least one point in eight of 10 games, it hasn't scored more than three goals in six straight.
"We've played a little bit too much on the defensive side," Bylsma said. "We need to play in the offensive zone better. We know exactly how playoff hockey is won and playing defense -- playing team defense, giving up two goals or less -- is where it's at."
