Team USA has set its lineup for the big rivalry matchup against Canada Tuesday night. With their tournament lives on the line, coach John Tortorella has made some significant changes.

Dustin Byfuglien, who was a surprise scratch for Saturday's stunning 3-0 loss to Team Europe, is back in the lineup. Also drawing in will be New Jersey Devils forward Kyle Palmieri, who sat out Saturday as well.

With two going in that means two had to come out and Tortorella made a decision that probably was personally difficult for him. Both of the Columbus Blue Jackets on Team USA's roster, Brandon Dubinsky and Jack Johnson, will be healthy scratches against Canada. Tortorella, who coaches both full-time in the NHL, had been singing their praises coming into the tournament, but neither looked particularly good in the game against Europe.

It does not appear Team USA will be making any changes in net. Jonathan Quick will get the start, with Ben Bishop backing up. Cory Schneider will not dress for the second straight game.

It's pretty simple for Team USA Tuesday. A win keeps their semifinal hopes alive. A loss of any kind means Thursday's game against the Czech Republic is nothing more than a glorified exhibition. These are the typical stakes in USA-Canada games of late, it seems.

With Byfuglien and Palmieri drawing into the lineup, Team USA should be a bit more threatening offensively. Tortorella said he could end up using the Winnipeg Jets defenseman at defense or forward and he will also see time on the power play, where he can be particularly dangerous no matter where he lines up.

Scratching Dubinsky is only surprising because it had seemed that he made Team USA primarily thanks to his work as Sidney Crosby's chief irritant while in Columbus. That, and the fact that Duninsky is the only left-shot center on the American roster, were big influences in his making the team amid his less-than-stellar production in the NHL. It's going to be tough to get in Crosby's face from the press box, but based on the early returns, he wasn't fitting with what the U.S. was trying to do up front. Dubinsky also took a costly double-minor penalty for high-sticking Zdeno Chara of all people in Saturday's game.

Tortorella scratching the two players he was believed to have had a huge say in adding to the roster shows that desperation trumps sentimentality or familiarity. He'll just have to hope it's not too late to change Team USA's fate in the tournament.

That doesn't mean the U.S. head coach is done making puzzling roster decisions, though.

Tortorella has also said that he plans to give Justin Abdelkader more ice time. He lined up in practice alongside Derek Stepan and Patrick Kane, which is a bit of a curious spot for one of Team USA's primary grinders. It is similar to how he is used with the Detroit Red Wings, though, as he skated with Henrik Zetterberg and Pavel Datsyuk for a portion of the last season. We'll have to see if it pays off for USA.

Over on the other side of the red line Tuesday night, Canada will dress the same lineup it did in a 6-0 win over the Czech Republic. That means Claude Giroux, Jake Muzzin and Braden Holtby will all be sitting out.
