Washington (AP) The Washington Capitals, Buffalo Sabres and Edmonton Oilers are set to play their playoff games in 2018.
The NHL announced the dates Tuesday night in advance of a scheduled playoff debut.
It was not clear how many playoff games would be played at Nationals Park, or if the Capitals would have to make changes to their schedule in order to accommodate the event.
The NHL said the teams were expected to begin their playoff runs on April 23.
The Capitals are expected to face the Tampa Bay Lightning in the first round, which is expected to be the first of the postseason series.
