Transcript for Guardian angel helps Loyola Chicago basketball team enter the Sweet 16
Finally tonight, you don't have to love basketball to love this next story. Just know a team that is now on fire is giving credit to a 98-year-old nun. The power of sister Jean, on the court. They did it. With just seconds left, a last minute shot, and a lucky bounce. And just like that, Loyola Chicago entering the sweet 16. And the dream is alive! Reporter: We've told you before about this team, early on upsetting the university of Miami with that buzzer-beater three-pointer. But what makes them special is their secret weapon. A 98-year-old nun who is cheering, and praying for them every step of the way. Their guardian angel right there, sister Jean. That was all you! Reporter: After last night's big win, each player giving her a hug. Her story going viral. The internet exploding with sister Jean memes, like this one with her in a wheelchair, dunking over Tennessee. She's so cool, she has her own custom made Nikes. Just five feet tall. Right there in the huddle, this was just before the start of the game. Don't let those Tennessee team members scare you with their height. Height doesn't mean that much. Reporter: But truth be told, even sister Jean didn't have them advancing this far in her own brackets. I just thought they wouldn't go to the sweet 16, and now we may go even more than that. We will all be watching and rooting. Thanks for watching. I'm Tom llamas in New York. Have a great evening. Good night.
