This could be the dirtiest play in sports history ... a scumbag college basketball player straight-up punched an opponent in the FACE after shooting a 3-pointer ... and the video will piss you off.
This all went down on Monday night ... when Division III teams Fitchburg State and Nichols were playing in Massachusetts.
The guy who throws the punch is Fitchburg junior guard Kewan Platt ... ironically enough, he's a criminal justice major.
The man on the receiving end of the punch is Nichols guard Nate Tenaglia.
People are RAGING about the video on social media .
