One day before entering the bubble in Edmonton, Alberta, the national junior teams of Finland, Russia, and the United States have named their final rosters for the 2021 IIHF World Junior Hockey Championship.

Starting off with Finland, as usual, they will have a well-rounded roster and are a gold medal threat. This year, they are in a group with Canada, Germany, Switzerland, and Slovakia.

There are several prominent names on Finland's final 25-man roster. Florida Panthers 2020 1st round pick Anton Lundell, 16-year old, soon to be 17, Brad Lambert (who is a projected top three pick in 2022), Winnipeg Jets first round pick in 2019, Ville Heinola, and goaltender Kari Piiroinen.

Russia will look to avenge their loss to Canada in the gold medal game from last year's tournament. The Russians will be in a group with Sweden, the USA, the Czech Republic, and newly promoted, Austria.

Their 25-man roster includes quite a few high quality players. Starting in net with the return of Yaroslav Askarov, Nashville's 2020 first round pick. On defence, they will be led by New Jersey's 2020 first round pick, Shakir Mukhamadullin. Up front, Vancouver Canucks 2019 first round pick, Vasili Podkolzin, Nashville's 2019 second round pick, Egor Afanasyev, and Toronto Maple Leafs 2020 first round pick, Rodion Amirov will lead the offence.

Finally, the United States are going into the 2021 World Juniors with two key players missing. Leafs prospect, Nick Robertson was not named to the final roster because Toronto wants him to attend their training camp which will likely begin during the World Juniors. Bruins prospect, John Beecher was not named to the USA roster, and it's being reported that he's tested positive for COVID-19.

The USA roster will feature two returning goaltenders, Flames 2019 seventh round pick, Dustin Wolf, and Panthers 2019 first round pick, Spencer Knight. Flyers 2019 first round pick, Cam York, will take charge of D-core, while Montreal Canadiens 2019 first round pick Cole Caufield will lead a potent team USA forward group.

Team USA will also include forwards Trevor Zegras, Alex Turcotte, Arthur Kaliyev, and Matthew Boldy.

Final rosters have to be submitted by tomorrow night, before the 10 nations enter the Edmonton Bubble. On Friday, the hosts, Canada, named their 25-man roster.

Finland will kick off their tournament on Christmas Day against Germany at 6 pm ET/4 pm MT (local time), while Russia and the United States will face off against each other on Christmas Day at 9:30 pm ET/7:30 pm MT.

All 10 exhibition and 28 tournament games can be found on TSN and RDS in Canada.
