Kansas, for the third straight season, is one win from advancing to the Final Four.
The Jayhawks (30-7), the top-seeded team in the NCAA Tournament's Midwest Regional, downed No. 5 seed Clemson (25-10), 80-76, in a Sweet 16 battle on Friday night at CenturyLink Center.
The victory, which looked like it was going to be easy (KU led by 20 early in the second half), turned out to be difficult as the Tigers cut the gap to six points with 2:27 left and four with :14.5 to play.
The Jayhawks' win sets up an Elite Eight contest on Sunday against another ACC team — either Syracuse or Duke, who played later Friday night — with the winner advancing to the Final Four a week from Saturday in San Antonio.
