Roberto Luongo will be back in goal Sunday but the Vancouver Canucks plan no other changes when they face the St. Louis Blues to complete a four-game homestand.

Coach Alain Vigneault ran a full practice Saturday at Rogers Arena, with the emphasis on penalty killing and power play, and later said he wasn't terribly upset with Friday's 4-3 loss to the Dallas Stars. The Canucks squandered a 3-2 third-period lead in the game, the third time this season they have lost when leading after 40 minutes. The Blues and Canucks will face off at 6:05 Sunday.

"Sometimes those bounces are just going to happen in a game and it's just not going to be there for you," said Vigneault, whose skaters had won six straight before the Friday collapse. "As far as the way our guys prepared and played and skated and hit, I mean, they were pretty good last night."

The Canuck power play went 0-for-3 against the Stars and is on a 4-for-39 swoon that has seen it tumble to 20th in the league at 16.4 per cent. The Blues, by contrast, have the NHL's top power play at 35.8 per cent.
