Sherron Collins and Cole Aldrich kept Kansas from being bumped off early by the North Dakota State Bison.
Collins scored a season-high 32 points and went basket for basket with NDSU star Ben Woodside, and Aldrich had 23 points to help the defending NCAA champions hold off the 14th-seeded Bison 84-74 in the first round Friday.
Woodside played all 40 minutes and scored 37 points, and fellow senior Brett Winkelman tirelessly contributed 15 points and 12 rebounds to keep third-seeeded Kansas (26-7) from getting comfortable until the final minutes.
In their first season of eligibility for the NCAA tournament after a four-year waiting period following their move up from Division II, the Bison (26-7) proved they indeed play pretty good basketball up on the prairie.
The Jayhawks will play former Izzo assistant Brian Gregory's University of Dayton Flyers on Sunday.
