STATE COLLEGE, Pa. (AP) – Traevon Jackson made a contested 3-pointer at the buzzer and finished with 15 points, and No. 22 Wisconsin survived an upset scare from Penn State with a 63-60 win Sunday in its regular-season finale.  The Badgers (21-10, 12-6 Big Ten) went the length of the court with less than 4 seconds left. Jackson pulled up at the wing and made the 3 over the outstretched arm of Kevin Montminy.  Officials upheld the basket on the review, and anxious fans at the Jordan Center let out a collective sigh of disappointment.  D.J. Newbill had tied the game with 5 seconds left with a jumper. Wisconsin nearly threw the ball away on the ensuing inbounds, but managed to hold on to possession in the scrape after the officials called a tie-up.  Jermaine Marshall finished with 23 points for Penn State (10-20, 2-16).
