Ron Artest's Son: Posterized in Drew League Game

Metta World Peace's son is a rising star in the high school basketball world -- but he got brought right back down to earth during a Drew League game ... and it was all caught on video.

16-year-old Ron Artest III took the court with some legit ballers in the prestigious L.A. league last week -- and got a real-life experience about what it's like to get dunked on ... hard.

The guy with the ball is Sek Henry -- who started 99 games during his 4 years at Nebraska before playing pro ball overseas. Point is, dude can play.

Artest went up for the block ... it didn't go well.

Don't worry, Ron, it even happens to the greats sometimes ... just ask your dad.
