The North Carolina (UNC) Tar Heels and the Wisconsin Badgers battle on Thursday in the Sweet 16 round of the 2015 NCAA Tournament.  The March Madness fourth-round game tips off at 7:47 p.m. ET and can be live streamed - or listened to - for free through any of the links provided below.

No. 1 Wisconsin hasn't tasted defeat since its loss to Maryland on Feb. 24.  Since then, the Badgers have gone on to win eight straight games, including Sunday's 72-65 win over Oregon in the third round of the NCAA Tournament.  Junior forward Sam Dekker led with 17 points, forward Frank Kaminsky turned in a big game with his 16 points and seven rebounds and sophomore Nigel Hayes added 14 points.

"We're definitely excited and thrilled to be there, but we're not as in awe or shocked as we were last year," Hayes said after the win, via ESPN. "Last year, we were jumping around up and down on the court, celebrating. This time, it was 'Hoo-rah, good job guys. We have the next game to take care of.'"

No. 4 North Carolina earned its spot in the Sweet 16 by defeating Arkansas on Saturday, 87-78.  Sophomore forward Kennedy Meeks, however, sprained his left knee in the win and is a game-time decision, according to the Associated Press.

"I'm doing pretty well," Meeks told the Associated Press. "I'm jumping a little bit more and trying to do all the right things so I can take care of my knee."

The Tar Heels' frontcourt will need all the help it can get against the much taller Wisconsin big men.  Although Meeks is three inches shorter than Kaminksy, he outweighs the Badger's big man by 30 pounds.  North Carolina also has 6-foot-9 forward Brice Johnson, for whom Kaminsky had nothing but praise.

"His combination of size and athleticism isn't very common in college basketball," Kaminsky said. "He does a great job of attacking the glass, getting things done inside."
