Alston was arrested Aug. 27, 2007 after a confrontation with Wilbert Ashman of Long Island inside Club Stereo in Manhattan. Ashman told police he and Alston accidentally bumped each other, and during an ensuing argument the 31-year-old player cut him.
Defense lawyer Alberto Ebanks did not immediately return a call to the AP but told the Houston Chronicle that prosecutors found there wasn't anything to the case.
"They understand the case has no merit," he said. "We're obviously pleased with the outcome, as pleased as can be when the case had no merit and understand should never have been charged in the first place."
