Bill Self did not coach in Kansas' 72-71 upset loss to Arkansas in the second round of the NCAA tournament on Saturday.
Self continues to recover from a procedure last week after complaining of chest tightness and balance concerns. He underwent a heart catheterization, had two stents placed for the treatment of blocked arteries and was discharged from the University of Kansas Health System on Sunday.
Assistant Norm Roberts once again served as acting head coach for the Jayhawks, as he has since the Big 12 tournament. Kansas went 3-2 in Self's absence.
"Our guys have been terrific all year," Roberts said. "They fought to the very end, made huge plays. It was tough not having Coach here, but we don't make any excuses. We have to line up and get it done, and we came up a little bit short today."
Speaking before Saturday's loss, Self said he was feeling "tons better" but needs a little more time to recover from the procedure.
"Got my energy back to an extent, sleeping better, doing things that they said were important to be on the mend quickly," he said. "Just probably not quite quick enough."
Self, 60, added that after consulting with his doctors Saturday, the determination was that the most prudent course of action was that he "rejoin the team full speed next week."
Roberts, 57, also replaced Self for four games during the season when Self was suspended by Kansas as part of self-imposed sanctions stemming from the FBI investigation into college basketball corruption.
Self had been attending Kansas practices since the Jayhawks arrived in Des Moines, Iowa. Roberts said that because Self was present, the Jayhawks' routine hadn't changed much.
