Three different times the Nebraska Cornhuskers built what looked like a comfortable lead and three times Wisconsin came back. The last comeback fell short in a 63-59 loss on the road Tuesday night.  Ethan Happ had an effective performance with 19 points and 11 rebounds.  Brad Davison had 15 and connected on a 3-pointer with one second left to cut the margin to 62-59.  The Badgers made 10 critical turnovers and hit just five-of-19 long-range shots.  The Huskers were good on 21-of-28 free throws, while Wisconsin was just four-of-10.  The Badgers take a week off, then try to break the two-game losing streak at number-13 Purdue.
