The Bruins may be done for the spring, but David Krejci and David Pastrnak are not.

According to Josef Jandac, the coach of the Czech Republic national team, there’s an agreement that his squad will be receiving a boost from the Boston duo as they join the Czech Republic for the 2018 IIHF World Championship in Copenhagen. Jandac also said that he plans to play the Krejci-Pastrnak duo on the same line.

The 21-year-old Pastrnak jumps to the Worlds after posting 20 points in 12 postseason games for the Bruins, making him just the 20th player in NHL history to record at least 20 points in a playoff run at 21 or younger. Pastrnak also established career-bests in goals (35), assists (45), and points (80) in the regular season.

Pastrnak recorded one goal and seven points in eight games at the 2017 IIHF World Championship, and also skated in three games for the Czech Republic at the 2016 World Cup of Hockey in Toronto.

The 32-year-old Krejci joins Pastrnak on the international stage after a 44-point regular season and postseason run that included three goals and 10 points in 12 contests.

Not healthy enough to participate in the 2016 World Cup of Hockey (hip) or last year’s World Championship (knee), this will be Krejci’s first time playing for his home country since the 2014 Winter Olympics in Sochi.

The Bruins will go through their locker clean-out day and media availability Wednesday morning at Warrior Ice Arena, where more players could state their availability for the tournament, which is already underway.
