Carnell Davis -- a freshman wide receiver on the Rutgers football team -- was reportedly knocked out by a violent punch in a street fight ... and the whole incident was apparently caught on video.
It's unclear where and when the altercation took place ... but The Press of Atlantic Cityreports the 6-foot-1, 175-pound wideout is the shirtless man wearing blue shorts in the footage that was posted on social media this week.
In the clip, you can see the man purported to be Davis, get into a tiff with another shirtless male in a red hat apparently over comments about Davis' mother.
