The first of the far-right Proud Boys to be busted last year in a brawl outside the Upper East Side Metropolitan Republican Club was sentenced on Thursday to 10 months worth of weekend jail stints.

Geoffrey Young, 38, will serve the time as punishment for misdemeanor rioting and attempted assault, the top charges against him, and to which he’d pleaded guilty on June 20 in Manhattan Supreme Court.

In all, 10 Proud Boys and protesters who’d mixed it up after a speech by the group’s founder, Gavin McInnes, were charged in the October brawl outside the GOP club’s headquarters, a townhouse at Third Avenue and East 83rd Street.

Of those 10, seven have pleaded guilty to misdemeanors and three are still awaiting a trial or plea deal on their felony or misdemeanor charges, the Manhattan DA’s office said.

In all, five of those arrested have been sentenced.
