Bertuzzi, who has been nursing a groin injury, will miss up to a month with mononucleosis.
"Bert's got mono," Red wings coach Mike Babcock said Saturday. "When we talked to him [Friday], we knew something was wrong. He's got mono, so he's going to [miss] a chunk of time."
Asked if it will be weeks, Babcock replied: "Oh yeah, for sure. Probably."
Bertuzzi, who turns 38 on Feb. 2, could go on injured reserve, which would clear a spot for injured Darren Helm (back) to return.
Bertuzzi has 751 points in 1,093 career games.
Colaiacovo, who became an unrestricted free agent this summer, was not brought back by the Blues and signed a two-year, $5-million contract with the archrival Detroit Red Wings.
Colaiacovo, 29, arrived at the arena Saturday morning and had to remind himself where he needed to be.
"Actually, I got locked out when I came in," Colaiacovo quipped. "I didn't know where to go. I'm still used to being a home player here. I didn't know where the visiting teams were supposed to go.
"I've seen a lot of familiar faces and it brings back a lot of good memories. I obviously still have a lot of great friends on that team. I saw them last night and saw them again this morning. A lot of mixed emotions going through me today. The adrenaline's going to be rushing through me tonight. I know that the crowd's going to be rocking. It's a new opportunity for me, a fresh start. I'm looking forward to making the most of it."
ST. LOUIS -- The look in Vladimir Tarasenko's eyes said it all.
The St. Louis Blues' 2010 first-round draft pick is feeling like a kid in a candy store, excited to be realizing a dream. On the other hand, when the 21-year-old steps onto the ice for his first National Hockey League game against the Detroit Red Wings tonight (7 p.m. on FSN, KMOX 1120-AM), the nerves will be fast and furious.
"I'm very excited because this is my dream. It's a dream come true," Tarasenko said at the morning skate. "I'm a little bit nervous because this is my first game in the National Hockey League. I never thought I would get here."
ST. LOUIS -- The defending Central Division champion St. Louis Blues will face a still formidable Detroit Red Wings team Saturday, even though they will be opening a season without the great Nicklas Lidstrom for the first time since 1991.
"It's the Detroit Red Wings, so it just looks the same to us," Blues coach Ken Hitchcock said. "They just fill in the gaps.
"Everyone thought when (Steve) Yzerman left, it was going to be all over and they did just fine. I'll reserve judgment until we see how they look without him in there. To me, they know how to play the game the right way."
The 25-year-old Oshie, who is coming off of career highs in goals (19), assists (35), points (54) and games played (80), was a restricted free agent who made $2.35 million on a one-year contract in 2011-12. He was the Blues' first-round pick (No. 24) in the 2005 NHL Draft. His 54 points were tied for the team lead last season.
"We're obviously excited to have T.J. under contract as he enters the prime of his career and to know that we'll have him through that portion," Blues general manager Doug Armstrong said. "It's very rewarding and we think he's a big piece of our team from last year and he's a big piece moving forward."
The Blues and Oshie were set to have an arbitration hearing Friday at 10 a.m. ET, when both sides would have presented their respective cases for a contract, which would be either a one- or two-year term of the team's choice. A deal between the two sides at some point leading up to the hearing always seemed like the most likely end result.
"Arbitration is just a tool that both sides have available to them," Armstrong said. "It's just a piece of the process. We exchange briefs and we get an idea where each side is coming from. I think everyone's comfortable with the business side of it that you try not to have any hangover of emotion based on an arbitration hearing.
"We knew today at 9 a.m. (CT), we were going to put T.J.'s fate in someone else's hands and we both decided it was best to try and see if we can work out something together."
After playing in only 49 games during a 2010-11 season that included some off-ice issues, the Blues gave Oshie a one-year deal to prove himself. Oshie proved worthy of a long-term commitment with a solid season that helped the Blues to the second-most points in franchise history with 109. Adding veteran coach Ken Hitchcock also was a catalyst in Oshie's success.
"We certainly thought he had a good, productive season last year," Armstrong said of Oshie. "A lot of the things that we were looking for as far as consistency on the ice, the ability to play 80 games was there. I also think with the coaching change, I think he embraced the new coach and someone with Ken's experience obviously he became a valuable player for our franchise with the amount of ice time he got. He and David Backes mirror each other. We know what David means to our team, so I just felt knowing Ken was here and knowing what T.J. means to the team and how he's coached by Ken just made it a natural movement to get him signed for a longer term as possible and we were able to do that."
Add this contract to the recent signing of David Perron to a four-year deal, and the Blues now have a good portion of their core group under contract for the long term. Defensemen Alex Pietrangelo and Kevin Shattenkirk will be restricted free agents after the 2012-13 season and are likely the next targets for long-term deals.
ST. LOUIS -- Both the St. Louis Blues and Los Angeles Kings are perfect on the road in these playoffs, but for the Blues, they have home ice and were one of the best teams at Scottrade Center this season with a 30-5-6 regular season record and two wins and an overtime loss against San Jose in the first round.
But the Kings won all three games at Rogers Arena against the Vancouver Canucks, who won the Presidents' Trophy as the NHL's regular-season champions.
"We were a pretty confident group going in," Brown said of the road success. "I think a lot of players have been in this room for a while, have been playing together for a while.
"We understood the situation we were in and we understand the type of team we have. Knocking off the top seed Vancouver obviously adds a little bit of confidence, but I think we all understand that St. Louis is a different type of beast and it's going to be a hard series.
"They're just a different team than Vancouver. We found a way to be successful against Vancouver and now it's a new challenge. There's different things that we have to do to be successful against the Blues. A lot of it comes down to work. That's the one thing you can control, which is a good thing. To beat a team like St. Louis, you've got to be willing to do all those little things on every single play."
The Blues hope to be as relentless as the Kings are advertising them to be.
"Just a strong defensive game like we had all year and in the San Jose series," defenseman Barret Jackman said. "We're going to really have to work for our chances, throw everything we can on net and get second chances. It's going to be predictable hockey from both sides, a hard-fought series and it's going to start right from the first drop of the puck."
Added veteran center Jason Arnott: "We just can't get out of our element. We have to stick to our system. You can't get frustrated, that's the biggest thing. We know we're going up against a great defense and a great goaltender. They play a solid defensive game. It's going to be tough and frustration's going to creep in here or there, but we just have to stick to our system and play to our game plan and keep funneling pucks as much as we can and hopefully a few go in for us."

I always feel the pressure to produce offensively. It's disappointing and frustrating when you can't help out your team the way you're supposed to.
