Penguins right wing James Neal is out indefinitely after sustaining a concussion.

Neal played in the team's 2-0 victory on Tuesday against Washington.

Following Wednesday's off-day, however, Neal told team doctors that he “didn't feel right,” according to coach Dan Bylsma said.

Later on Thursday, he was diagnosed with a concussion.

Neal also sustained a concussion late in the 2013 regular season.
