Wilson put Washington on the board Tuesday with a first-period goal before leaving the game shortly after. He returned briefly during a TV timeout to take a few laps around the ice and then departed again for good with a member of the training staff.
The No. 8 seed Capitals carried on without their agitator, leveraging that early lead from Wilson to top the Presidents' Trophy-winning Panthers 4-2. They'll take a 1-0 series lead into Thursday's Game 2.
Whether Wilson will be a part of that matchup remains to be seen. Capitals coach Peter Laviolette shared a minimal update on Wilson's status after the game, saying Wilson was being minded by the team's medical staff and the club would potentially know more on Wednesday. Laviolette also wasn't clear on how exactly Wilson was hurt, theorizing that it might have been when he tried to check Panthers defenseman MacKenzie Weegar and ended up going hard into the boards.
Losing Wilson for any length of time would be a tough blow to Washington. The winger scored 24 goals and 52 points in the regular season while averaging 18:35 per game.
