Penguins center Sidney Crosby, who is recovering from a concussion, skated at the team's practice facility in Cranberry Thursday.
Coach Mike Sullivan said in a conference call that Crosby is day to day.
Crosby was injured early the Penguins' 3-2 overtime loss Monday in Game 3 of their second-round series against Washington when Capitals defenseman Matt Niskanen cross-checked him in the head and did not play in the Penguins' 3-2 victory at PPG Paints Arena on Wednesday night.
Crosby missed parts of the 2011-12 and 2012-13 seasons because of concussion-related issues. After another concussion in October 2016, he sat for the first six games. That time, he started skating relatively soon after his injury but didn't actually play until about two weeks later. Sullivan, asked if this recovery would follow a similar template, opted not to elaborate.
"I think what separates Sid from most other players is his ability and his willingness to play in the battle areas," Sullivan said. "He has a blue-collar element to his game even though he's an elite player, and I think that's what's allowed him to have the success that he's had."
The Penguins lead the series, 3-1, and could clinch a spot in the Eastern Conference final with a victory in Game 5 Saturday at 7:15 p.m. in Washington.
