Washington goaltender Tomas Vokoun, who's been troubled by a groin problem, left the Caps' game at Boston late in the first period with an apparent lower-body injury.
Vokoun stopped all seven shots he faced before he simply left the ice with 1:35 left in the first period, skating to the bench and walking down the tunnel to the dressing room. Michal Neuvirth replaced him and finished out the period, which ended scoreless. Braden Holtby, scratched against Boston, left his spot in the press box during the first intermission to dress as Neuvirth's backup.
Vokoun hadn't played since March 16 and was playing for just the fourth time this month.
It was uncertain exactly when and how Vokoun was injured, though it's possible he aggravated the groin problem. Boston defenseman Andrew Ference took a shot with just over 1:35 left and Vokoun had to slide from right to left on his knees to make the save. When he got up, he appeared to be in pain.
