America almost lost a legend Wednesday night ... but thankfully, Joel Embiid's hops saved the day.
Golden Globe winning actress Regina King had court side seats at MSG for the Sixers and Knicks game ... but it might've been TOO close to the action considering what went down in the 3rd quarter.
Embiid went chasing after a loose ball that was heading for the stands,forcing him to jump over R.K. in the process ... and you can tell by King's face -- she was SHOOK.
Embiid ended up kicking the dude behind King square in the chest .
