Troubled ex-New Jersey Nets player Rafer Alston fouled out at a strip joint -- bashing another man on the head with a beer bottle during a booze-fueled brawl, a new lawsuit charges.

The former NBA athlete, 35, who's originally from Jamaica, Queens, attacked fellow Perfection Gentleman's Club patron Erick Franceschini, 32, of Milford, Conn., during a knock-down-drag-out free-for-all in July 2010, according to papers recently filed in Queens Supreme Court.

Alston smashed Franceschini with the bottle during a dispute that began in the Woodside, Queens, club and spilled out on the street, said Franceschini's lawyer, John Rapawy.

Alston was not involved in the fight in the bar, Rapawy said, but the lawyer claimed the hoopster attacked Franceschini in the street.

Alston -- known in his playing days as "Skip to My Lou" because he was fast and light on his feet -- "unjustifiably assaulted and [beat]" Franceschini, Rapawy told The Post yesterday.

"My client had 12 staples in his head. He suffered a concussion," the lawyer said.

Rapawy said he and his client filed a police report, although Alston was not arrested. Police sources confirmed an assault complaint had been filed against Alston, but said it was sealed and they could not give out any more information.

The lawsuit seeks unspecified damages from the millionaire ex-hoopster, who now lives in Boca Raton, Fla., as well as the strip club.
