Canucks associate coach Rick Bowness said prior to the game that the defenseman was a "game-time decision" for the matchup against the Nashville Predators.
Salo was among the last Canucks off the ice after an optional skate Tuesday morning, hours before Game 3 of the series. Salo suffered an undisclosed injury in Game 6 of Vancouver's opening series against the Chicago Blackhawks.
The 36-year-old defenseman missed the first 4½ months of the season recovering from a torn Achilles tendon but was the Canucks' best all-around defenseman the year before. He had one goal and was minus-2 the first five games of the playoffs.
Vancouver, winner of the NHL's Presidents' Trophy, now holds a 2-1 edge in its Western Conference semifinal against Nashville.
