The team captain and two-time NHL MVP scored during an organized scrimmage Saturday. Coach Mike Sullivan declined to offer specifics on what happened to Crosby in the immediate aftermath, saying he was "not permitted to comment."
On Sunday, assistant coach Mark Recchi sidestepped a question about Crosby's status.
"You're trying the wrong guy," Recchi said. "I think you know the league's stance right now. Sorry about that."
Although he left the scrimmage early, there was no indication of a serious issue, according to ESPN's Emily Kaplan.
The Penguins are about two weeks out from facing Montreal in the qualifying round of the 24-team NHL postseason. Pittsburgh will be in the Toronto pod when play resumes.
