Dickinson tumbled and threw a back heel to the face of Brown, which turned the competitive play into a chippy one as players needed to be separated.
After review, the Jayhawks’ 24-year-old leading scorer and rebounder was issued a Flagrant 2 and ejected from the game.
“I didn’t think at the moment and nor now do I feel it a warranted a level-2,” Kansas coach Bill Self said after the game. “In my opinion, it’s probably a coin flip whether it’s a level-1 or a level-2.”
Dickinson is now in his fifth college year and his second at Kansas after starting his career with Michigan. Accusations of being a dirty player have followed him for most of his career.
