The No. 7 Duke Blue Devils blew out the Clemson Tigers by 18 points on the road Thursday, but there was a lot of drama thanks to a ridiculously dirty foul by Clemson guard David Collins against Duke's Wendell Moore Jr.

Late in the first half, Moore was streaking down the court for a fast-break dunk when Collins undercut him in the air. Moore went down hard in a scary foul:

Duke head coach Mike Krzyzewski was absolutely livid (he later called the play “dangerous”) and players from both teams yelled at each other as chaos ensued. Collins was rightfully ejected from the game.

Naturally, Twitter went wild in reaction to this dirty foul:

There's plenty more where that came from, and it's justified. You know it's bad when people are feeling bad for Duke. That kind of play is totally unacceptable. Collins had zero chance of making a real play on the ball and had no business doing what he did. Perhaps there was no malicious intent there, but this was an obvious mistake that should get punished.

To his credit, Collins did take to Instagram after the game to explain himself and apologize for his actions:

But, again, even if Collins didn't mean anything by the play, it was still a dangerous one that could have really hurt the Duke forward. Luckily, it seems as if Moore is okay. He wound up playing 33 minutes in the 18-point victory that moved the Blue Devils to 20-4 on the season.
