Backstrom took part in the Capitals' full workout Thursday before departing with the team for a West Coast road trip. Washington plays at San Jose on Saturday.
Backstrom was elbowed by Rene Bourque in the third period of the Capitals' 3-1 win over Calgary on Tuesday. Bourque has been suspended five games by the NHL for the hit.
Backstrom underwent tests to determine if he suffered a concussion. He said he felt fine after practice, and coach Dale Hunter said the 24-year-old forward is doing better than expected.
Backstrom has a team-high 42 points for the Capitals this season.
