A Youngstown State football official has just been booted from the sidelines for the foreseeable future ... after he knocked an opposing player to the ground with his shoulder.
The scene was pretty wild ... during YSU's game against the University of Northern Iowa on Saturday -- Panthers star receiver Quan Hampton was speeding toward the YSU sideline when Director of Player Personnel Tim Johnson appeared to throw himself at the guy.
Hampton took Johnson's shoulder at full speed ... and tumbled to the ground awkwardly -- clearly fortunate to not suffer any serious injures.
