Forwards Martin Lang and Martin Rysavy were among 37 skaters and five goaltenders named to the event, which will decide who will represent their country at the tournament in Edmonton beginning Boxing Day.
Lang, 19, joined the Warriors at the trade deadline last season in the deal that sent defenceman Libor Zabranksy to the Kamloops Blazers. He would go on to score eight goals and 24 points in 26 games with the Tribe, capping the campaign with 15 goals and 43 points in 57 games.
Lang has since been loaned by the Warriors to a handful of Czech league U20 and professional teams, putting up four goals and 10 points in 10 games -- including two goals and seven points in two games with HC Plzen in the Czech U20 loop.
Rysavy, 17, was selected sixth overall by the Warriors in the 2020 Canadian Hockey League Import Draft. He played a game for HC Vitkovice in the U20 league this season before suiting up his hometown HC Prerov in the Czech Second Division, scoring twice and recording five points in his first six games.
The 2020 World Junior Hockey Championship will run from Dec. 25 through Jan. 5 in a bubble in Edmonton, with no fans and strict precautions to protect players and officials from COVID-19.
Moose Jaw Warriors defenceman Daemon Hunt and general manager Alan Millar are currently in the middle of a two-week quarantine with the Canadian National Junior Team selection camp in Red Deer.
