Perry Ellis returned from an injury to add 11 points for the top-seeded Jayhawks (26-7), though their leading scorer limped off the floor after getting tangled up late. Ellis never went back into the game after trainers checked on his right knee.
Still, his return combined with the inspired play of Selden helped push a mercurial Kansas team into Saturday night's title game for the 11th time. The Jayhawks will face the winner of the other semifinal between second-seeded Iowa State and No. 3 seed Oklahoma.
Rico Gathers had 11 points and 13 rebounds, and Kenny Chery added 20 points for the fourth-seeded Bears (24-9), who should still feel quite secure heading into Selection Sunday.
