The participation national U20 teams can register up to three goaltenders and 20 skaters born in 1996 or later. At the first directorate meeting each team has to register a minimum number of two goalkeepers and 15 skaters and additional players can be added up to two hours before a game until the maximum roster size is reached.

The Russian national team trimmed its roster to three goaltender, nine defencemen and 13 forwards. Defenceman Nikita Lyamkin and forwards Arkhip Nekolenko, Yakov Trenin and Artyom Zhelezkov had to leave the camp and two more players will be cut for the start of the tournament.

Slovakia trimmed its roster to the World Juniors size of 20 skaters and three goaltenders. From the initial camp goaltender Christian Pavlas, defencemen Andrej Hatala, Jakub Melisko and forwards Filip Ondrus, Samuel Solensky and Jakub Tatar didn't make the cut.

Sweden cut two players today. After the injury of defenceman Sebastian Aho last night, two more players had to leave the team for the final cut being forwards Fredrik Olofsson and Lukas Vejdemo.

The Czech roster after the exhibition games contains three goalies and 21 skaters of which one player will have to leave the team. Most recently forwards Vit Christov and Lukas Jasek were cut. From the original camp also goalie Karel Vejmelka, defencemen Lubos Adam, Tomas Havlin, Pavel Pycha and Dominik Rudl, and forwards Tomas Andres, Vaclav Karabacek, Filip Kutak and Lukas Vopelka are not with the team anymore.

Also last year's surprise team Denmark has trimmed the roster to 24 players and forwards Frederik Hoeg and Daniel Nielsen have been sent home. One more defenceman will be cut to form the final roster while it has been confirmed that NHL forward Nikolaj Ehlers won't be released by the Winnipeg Jets for the World Juniors.

Switzerland finalized its roster today with Tim Dubois and Johnny Kneubuhler having to leave. With Nico Hischier a 16-year-old prospect made the team. Forward Kevin Fiala declined joining the team and wants to focus on his AHL team Milwaukee Admirals. It would have been his third World Junior Championship.

Also Belarus, the team promoted to the top division, announced its roster. The players cut during the camp were defencemen Matvei Bozhko, Anton Grishanov, Yegor Ivanov and Vadim Klyavzo, and forwards Viktor Artyushenko, Dmitri Maisenovich, Kirill Markevich and Alexander Pilia.
