BOSTON (AP) – The NBA on Friday suspended Boston Celtics forward James Posey for one game for pleading no contest to reckless driving stemming from an incident in April.

Posey’s agent, Mark Bartelstein, said his client will appeal, calling the April 9 arrest in Miami Beach a “bad arrest.” Posey was arrested on drunken driving charges while he was a member of the Miami Heat.

“He wasn’t driving,” Bartelstein told The Associated Press. “This is a case where we need to make sure the NBA has all the information. Once they learn all the facts and what really happened, they will eliminate the suspension.”

Posey, 30, signed with the Celtics on Monday.

The NBA said Posey would serve the suspension, without pay, for the Celtics’ regular season opener against Washington on Nov. 2 in Boston.

Posey pleaded no contest – which is neither an admission of guilt nor a proclamation of innocence – about one month ago because he didn’t want the case to affect his opportunities in free agency, Bartelstein said.

Posey, a member of the Heat team that won the NBA championship in 2006, is entering his ninth season.

He completes an offseason that saw Boston acquire stars Kevin Garnett and Ray Allen along with role players Scot Pollard and Eddie House.
