Duke star Grayson Allen kicked an opponent and then lost his mind on the bench

ESPN

Duke's star guard Grayson Allen found himself in the middle of another controversy in which he kicked an opponent.

Late in the first half of fifth-ranked Duke's game against Elon, Steven Santa Ana of Elon drove to the basket and got tangled up with Allen. As Santa Ana spun away, Allen clearly kicked his leg out and hit Santa Ana. The two players then had to be separated.

The officials initially called a foul on Allen. However, they also reviewed the play and gave Allen a technical foul for the kick.

Allen was initially upset and pacing back and forth on the sideline. He eventually went to the bench, sat down, and went nuts, punching a chair.

This is not Allen's first rodeo. 

Last season, Allen was twice seen tripping opponents, including players for Florida State and Louisville.

Meanwhile, after coach Mike Krzyzewski spoke with the officials, he seemed to be upset and was yelling in Allen's direction. For several moments Allen just sat on the bench vigorously rubbing his face in a towel.
