CALGARY - The San Jose Sharks have gone from one win away from a series victory to one loss away from going home.

Sharks coach Ron Wilson is hoping the urgency that wasn't there Sunday night in a 2-0 loss to the Calgary Flames will return in the form of desperation on Tuesday night.

"Well it's the seventh game, if you don't win you're out. If I have to manufacture desperation, we are in dire straits. Our players know what's at stake," Wilson said.

Wilson said their is no excuses now for the lack of urgency that he witnessed Sunday night.

"We didn't have the sense of urgency that we need," he said. "We just didn't get to pucks first. We let them dictate the pace of play."

Forward Ryane Clowe said Sharks put themselves on the brink of elimination.

"The frustrating part was it wasn't as if we brought our game and they shut us down. I thought we shut ourselves down. We didn't do things to create scoring chances," Clowe said.

The history book is a thin one for San Jose when it comes to Game 7 showdowns. It will be the first time they've played in a seventh game in six years and it will the first time ever they've played one on home ice.

"Hopefully we can do what they did," said San Jose right-wing Mike Grier. "When we started to bounce back and get a little momentum, they took the energy from the crowd and got it going again. I'm sure our building will be loud, our fans will be into it and we can take some of that energy from them".

Grier has played in three Game 7s in his career winning twice and losing one.

"It should be a fun game and everyone should be looking forward to it," Grier says. "You don't get them that often so it's a special game."

San Jose is 3-2 in Game 7s but it's been a while since they've played one. Their last was a 1-0 loss in 2002 to Colorado in a Western Conference semifinal. Their last Game 7 victory was in 2000 when current Flame Owen Nolan scored the game-winner to clinch an opening round upset of the St. Louis Blues.

"It's a long, tough series, it's been hard fought, now it all comes down to one game. You have to be ready," said Sharks centre Patrick Marleau. "We've got to come out with some desperation, a little intensity, and be ready to play because now our backs are up against the wall too."

Expect to see Jeremy Roenick back in the line-up Tuesday after not playing in game six.

"We're at the point now where he needed a rest. We've been playing at a frenetic pace and I need J.R. fresh," explained Wilson. "He has three shots on goal, no points, and is minus-2 so I need to get a way to get J.R. freshened up and tonight was the night."

On a night when they were shut out on just 21 shots, the spotlight was on the Sharks not scoring and the most prominent one was left-winger Milan Michalek. Second on the team in goals (24) and first in shots on goal (233) in the regular season, Michalek has no points and just five shots on goal.

To sum up Michalek's series so far in a single play was seeing him squander a glorious 3-on-1 opportunity late in the second period that could have tied the score 1-1.

Breaking in with Grier and Torrey Mitchell, Michalek hung on to the puck too long and eventually mishandled the puck not even getting a shot on goal.

"He went in there wanting to pass but they took that away and when he looked up Kipper was in great position and then he ran out of time, space, everything," said Wilson. "We have to get Milan going. It would certainly alleviate the pressure from other guys if we can get him to contribute."
