For video feed: Minnesota’s Gopher All Access will be showing all tournament games. It costs 9.95/month, but that will give you access to both Northeastern games.
For radio coverage: As always, WRBB will have the call. You can find that here. So if $5/game is too much for you, then make sure to tune into WRBB for free. And even if you do get the video feed, mute it and listen to WRBB anyways.
Northeastern will play Princeton today at 5 PM (EST). Tomorrow, they either play in the consolation game at 4 PM (EST) or the championship game 7 PM (EST), where their opponent will either be Minnesota or Niagara.
