The Canucks open their Western Conference quarter-final at home on Wednesday against the Los Angeles Kings and would not say if Sedin, who worked out for about 40 minutes with six team mates after Tuesday's practice, would be in the line-up.
"I don't discuss line-up decisions," said Canucks head coach Alain Vigneault, who added that Sedin will not talk to the media until he plays. "It's a unique injury ... When he's healthy he's going to play."
Sedin's twin brother Henrik would not comment on Daniel's status when asked on Tuesday even though he said a day earlier that his line-mate was "100 per cent."
Sedin missed Vancouver's final nine games of the NHL regular season after suffering a concussion in March when he was elbowed in the face by Chicago Blackhawks defenseman Duncan Keith.
The potential absence of Sedin, who led the Canucks with 30 goals in 72 games this season, could be a severe blow for a team still seeking its first Stanley Cup after losing in the final last year.
