The University of Denver confirms that Pettersen will be joining Team Norway for the Division I World Juniors -- but only after playing in this weekend's games for the Pioneers.
That likely means he'll miss Norway's opening game on Sunday and potentially their second game on Monday too. It looks like the D-I tournament doesn't have a playoff, just a straight round robin with the best team getting promoted.
