A teenage basketball player floored two of his opponents with vicious haymakers during a game earlier this month ... and the punches were so violent, TMZ Sports has learned cops are now investigating the situation.
The contest went down at around 6 PM on Jan. 3 in Georgia ... when Sonoraville High School was taking on Rockmart in Calhoun.
With a little less than half the tilt remaining, a Rockmart player could be seen on video shoving a Sonoraville athlete to the ground. Seconds later, after the boy had gotten up from the push, the Rockmart player leveled him back to the hardwood with a huge right hand.
