If all you're interested in is having Husker scores in your notifications, you can follow them on the Google app, and then you'll get a notification anytime there is an event going on with the score constantly updated (although it's a little behind).
Just open the Google app, click the menu button in the upper left, then click "Customize". On the next screen, under the heading "In your stream" you should see a bunch of topics, one of which is "Sports". Click on "Sports" and then you should get a page where you can set what teams you're interested in, and you can add various Husker sports.
