Kings president of basketball operations Geoff Petrie made the announcement Monday. Sacramento selected Robinson with the fifth overall pick in the NBA draft almost two weeks ago.
Robinson, the first unanimous first-team All-American since Blake Griffin, led the Jayhawks to the national championship game against Kentucky, where Kansas lost 67-59. He averaged 17.9 points and 11.8 rebounds in 31.8 minutes per game in his junior season and led the nation with 27 double-doubles. Robinson also was the Big 12 Player of the Year.
Terms of the deal were not announced.
