Coach Bill Self announced the departures of the two walk-ons Wednesday. Self said Buford plans to remain at Kansas to pursue his degree in business finance.
Henry transferred to Kansas from Memphis last year to join his brother Xavier, who jumped to the NBA after playing his freshman season. C.J. Henry played in 13 games for the Jayhawks as a redshirt freshman, averaging 5.6 minutes and 3.1 points.
"C.J. informed us toward the end of July that he was going to look into other options to further his basketball career," Self said. "At this date, I do not know if anything has officially been decided on what he will be doing or where he will be attending, but he has decided to leave KU. It's a decision I totally respect."
Buford, a 6-foot-3 senior guard, played in 36 games in three seasons for Kansas and was a member of the 2008 NCAA national championship team. He leaves with a career average of 1.7 minutes, 0.3 points and 0.5 rebounds per game.
"We, as coaches, have thoroughly enjoyed having Chase as a member of our program the last three years," Self said. "I totally understand -- this being his senior year and the time commitment involved -- that he wants to pursue some other interests and also enjoy being a normal college student for his final campaign."
