With a win today in Boston the Capitals can climb within one point of the Southeast Division lead.
Tomas Vokoun and Michal Neuvirth have shared the nets this season but neither has grabbed the No. 1 job.
Capitals defenseman Mike Green was suspended three games for his elbow to the head of Lightning forward Brett Connolly.
Alex Semin does not have a point in five games. Capitals coach Dale Hunter says he needs more from the 28-year-old winger.
If Mike Green is suspended, Dale Hunter must choose between Roman Hamrlik and John Erskine.
