LAWRENCE, Kan. (AP) — Kansas coach Bill Self said the student government at Iowa State sent him a letter this week apologizing for a pair of incidents that occurred in the aftermath of the Jayhawks' overtime win over the Cyclones on Monday night.

The first incident occurred after Self gave a brief postgame TV interview. An Iowa State fan made his way down the court and charged after Self, and had to be held back by security.

The second incident occurred on Twitter, where at least two fans made racist and threatening comments directed toward the Jayhawks' Elijah Johnson, who scored 39 points in the game.
