Ronnie Magro Pleads Not Guilty to Assault

That's one felony charge, G! Ronnie Magro told a judge today he's not guilty of third degree assault, stemming from his infamous fight on Jersey Shore.

Ronnie entered a plea in Ocean County Criminal Court, where he was arraigned for knocking Stephen Izzo out with "one shot" back in September 2009.

His next court date is set for April 7. Here's the fight in question:

Jersey Shore - One Shot Fight

Ron's violent tendencies were on display again on last week's Jersey Shore episode. While he didn't knock out Sammi ... things got really, really heated.

Hopefully he gets some anger management counseling ASAP.

As for the recipient of the one-hitter quitter in '09, what a moron. Who goes out of his way to fight a raging, alcoholic meathead? Not saying he deserved to be eating pavement like that in the clip above ... but we can see how it happened.
