Harrison and the Wildcats were upset 71-64 by the Badgers, spoiling their quest to complete a perfect season.
After the game, Harrison was sitting at the interview table with his brother,Aaron, directly to his left and forward Willie Cauley-Stein directly to his right.
A reporter directed a question about Kaminsky toward Kentucky's Karl-Anthony Towns: "Karl, could you talk about Kaminsky and what if anything is unique about defending him?" the reporter said.
Near the end of the question, a live microphone picked up Harrison muttering "F--- that n----" as his hand covered his mouth.
Social media immediately lit up with questions about what Harrison said accompanied by video clips of his response. The AP reviewed an audio recording of the press conference, and the phrase is audible, but muffled.
The team planned to speak with Harrison.
"We have no comment until we have had a chance to evaluate it," Kentucky spokesman Eric Lindsey said.
