The Sabres announced Thursday that Grigorenko would leave for Russia on Sunday.
The Russian Ice Hockey Federation on Tuesday had released a list of 29 players for a selection camp to be held Dec. 9-20 in Novogorsk, Russia, but Grigorenko's name was not on it.
Grigorenko, chosen No. 12 by the Sabres in 2012 NHL Draft, has played in the previous two WJC tournaments. He helped his country to a silver medal in 2012 after totaling two goals and five points in six games and a bronze in 2013 with two goals and six points in seven games.
The 19-year-old center had two goals and three points in 18 games for the Sabres this season. He has three goals and eight points in 43 NHL games.
Barrie Colts defenseman Aaron Ekblad believes it isn't easy finding a player who takes great pride in a strong defensive game in this day and age of high-octane offense.
So he wants NHL scouts and general managers to know not only can he bring that style of game, but his versatility on the back end has also enabled him to expand his hockey repertoire.
"I think GMs are also looking for a guy who will jump into the rush and score goals, so versatility is a big thing," Ekblad told NHL.com. "I'm sure that's what they look for; every so often you have to throw your weight around too. But obviously being steady and knowing your position is important."
Barkov, who has played in the tournament the past two years, will not be released by the Panthers, the team that selected him with the second pick of the 2013 NHL Draft.
"There's no way he's going anywhere but here," Panthers general manager Dale Tallon told the Miami Herald. "We have to let him grow. He's a big part of our future and our present."
Barkov has four goals and six assists in 28 games this season, and he's fourth among rookie forwards with an average ice time of 16:55 per game.
When the USA Hockey staff went about picking the roster for its selection camp for the 2014 IIHF World Junior Championship, one of the buzzwords was versatility.
"It's important to show that you're a versatile player, and on this roster you're going to see a lot of guys who can play a lot of roles with the team," said Jim Johannson, general manager of the U.S. WJC team and USA Hockey assistant executive director for hockey operations. "That's always helpful in short tournaments and not knowing injures and all those things."
Although there isn't a proven dynamic performer among the 26 players invited to the camp, which will run Dec. 15-18 at the University of Minnesota, Johansson and coach Don Lucia believe the seeds are in place for a strong showing when the WJC starts Dec. 26 in Malmo, Sweden.
Forward Radek Faksa, a 2012 first-round draft pick of the Dallas Stars, highlights this year's Czech Republic National Junior Team selection camp roster that will determine the team for the 2014 IIHF World Junior Championship in Malmo, Sweden, later this month.
The selection camp will take place in Rokycany, Czech Republic, on Dec. 13. Miroslav Prerost will coach the team.
Faksa, selected No. 13 by the Stars in 2012, will be seeking a third straight appearance at the WJC. He has two goals and four points in 12 games at the tournament; the Czechs have finished fifth the past two years.
Faksa has 12 goals and 20 points in 25 games for the Kitchener Rangers of the Ontario Hockey League this season, his third in North America.
Bolstered by four first-round NHL draft picks, three returning players and two 2014 NHL Draft-eligible prospects, USA Hockey on Wednesday announced the 26 players invited to the selection camp for the team that will comprise the U.S. National Junior Team that will play in the 2014 IIHF World Junior Championship in Malmo, Sweden later this month.
The United States selection camp will take place Dec. 15-18 in Minneapolis. It will include five practices at Mariucci Arena at the University of Minnesota as well as a pre-tournament game at Minnesota State University on Dec. 17. When training in Minneapolis is complete, the team will travel to Angelholm, Sweden, to continue the evaluation process from Dec. 19-23.
The final 22-player tournament roster will be announced Dec. 23.
Each played a key role in leading the Americans to their third gold medal in tournament history at the 2013 IIHF World Junior Championship in Ufa, Russia. This season, however, they've taken their vast talents to the NHL; Jones has nine points in 28 games with the Nashville Predators and leads all rookies with an average ice time of 23:55 per game, while Trouba has four points in 12 games with the Winnipeg Jets while playing 21:00 per game.
While they won't have a chance to defend their gold medal, it certainly didn't stop them from reminiscing about their championship run with NHL.com. The U.S. won the gold with a 3-1 win against Sweden.
Canada unveiled its selection camp roster Monday.
"We have spent a great deal of time discussing and debating the pros and cons of the situation in the context of what is best for Sean's continued professional development as a hockey player, as well as what is in the best interests of our team, our fans, and our organization," Flames general manager Jay Feaster said in a statement. "We have concluded that in light of the prominent role Sean has played on our team to date, and the role we project he will continue to play once he returns from his injury, that Sean will remain with our hockey club."
Tampa Bay Lightning goaltending prospect Andrey Vasilevskiy and 2014 NHL Draft prospect Ivan Barbashev are among the top names in a group of 29 players invited to Russia's pre-tournament camp for the 2014 IIHF World Junior Championship.
Vasilevskiy is one of four players invited who was part of Russia's bronze-medal winning team in 2013, and this would be his third WJC. A first-round pick by the Lightning in 2012 (No. 19), Vasilevskiy had a .950 save percentage in four games for Russia last year and a .953 save percentage in five games two years ago.
The other three players invited who were on the team last year are goaltender Igor Utinski (no action), forward Anton Slepyshev (one assist in seven games) and defenseman Andrei Mironov (one goal, one assist in seven games).
