Helene St. James Detroit Free Press Published 10:59 AM EST Dec 18, 2018 Detroit Red Wings prospect Filip Zadina is in holding mode. He suffered a lower-body injury this past Saturday, casting into doubt his availability for the World Junior Championship. General manager Ken Holland said Tuesday that Zadina “is day to day. See how he feels tomorrow.” Zadina, 19, has eight goals and nine assists in 26 games with the Grand Rapids Griffins. The plan had been for him to play Wednesday for the Griffins when they host Cleveland, and then the Wings would release Zadina to represent his native Czech Republic at the 2019 World Junior Championship, which runs Dec. 26-Jan. 5 in Vancouver and Victoria, British Columbia. But Zadina left Saturday’s game with a groin/hamstring injury. If there’s rapid improvement, Zadina still could be headed to the tournament. He dominated at last year’s event, scoring seven goals among eight points in seven games. The Wings see this year’s event as an opportunity for Zadina to boost his confidence in the midst of his first year of pro hockey.
