Matt Barnes has been suspended by the NBA for one game (without pay) ... after the L.A. Clippers forward pled "no contest" to interfering with the duties of a police officer.
According to the NBA, Barnes will serve out his suspension tomorrow -- when the Clippers play their season opener against the Memphis Grizzlies.
The punishment stems from an incident back in July -- when Barnes was arrested for driving on a suspended license and resisting arrest.
As we first reported, Barnes eventually pled no contest to misdemeanor interference with the duties of a police officer ... and his suspended license charge was dropped when he proved he had a valid license.
Barnes just tweeted about the NBA's decision, calling it a "joke" -- but wishing his team good luck in his absence. He'll be back on Friday when the Clippers face the Lakers.
