Boone Jenner received a three-game suspension from the International Ice Hockey Federation for a charging incident last week.
Jenner, a Columbus Blue Jackets prospect, is supposed to play a key third-line checking center role for Canada. He was assessed a five-minute major and a game misconduct penalty for charging after a late hit on Swedish defenceman Jesper Pettersson in the second period of an exhibition game Dec. 22 in Helsinki.
Pettersson was diagnosed with a dislocated shoulder and fractured wrist and will miss the World Junior Championship.
The IIHF based its decision on a video review of the hit, which it ruled was late and delivered with no intention to play the puck, and with Pettersson being in a vulnerable position.
Jenner will have to sit out Canada's first three games of the WJC: Dec. 26 against Germany, Dec. 28 against Slovakia, and Dec. 30 against the United States.
