The Penguins' 2017-18 season ended last month at PPG Paints Arena, with the Washington Capitals on the opposing bench.
That's exactly how their next season will begin.
The Penguins will open their 2018-19 season Oct. 4 at home against Washington, the NHL announced Wednesday.
The league will release full schedules for all teams Thursday.
The Penguins and Capitals have combined to win the last three Stanley Cup titles, facing one another on the way each time.
The Capitals ended the Penguins' 2017-18 season on May 7, winning their second-round series in six games en route to the franchise's first Stanley Cup championship.
