Stephen Jackson from Indiana Pacers hit by car and fired a gun in front of Night Bar

Stephen Jackson , Indiana Pacers player, fired a gun in the air, apparently in self-defense, outside a strip club early Friday after he was slugged in the mouth and struck by a car that sent him tumbling onto the hood, police said.Nobody was injured by his gunfire.

Jackson refused medical threatment at a scene, but sought a treatment at hospital after conferring with team trainer.

Jackson was at the Indianapolis club with teammates Tinsley, Marquis Daniels and Jimmie Hunter. Tinsley and Daniels also had guns in their cars, and all three armed players had weapons permits, Mount said, although Daniels' permit was issued by Florida.

Police were looking for the car that struck Jackson and three men believed involved.

Jackson told officers he fired his 9 mm pistol five times after he was hit in the mouth and tossed on the hood of the car.

The Pacers said Friday that all involved are cooperating with police, and none of the players at the strip club would be available to the media after practice Friday.

"Since this is an ongoing review of the matters that took place Friday morning, the Pacers will have no further comment at this time," the team said in a statement.

The NBA's drug policy says players who test positive for marijuana face rehabilitation, fines and suspensions, depending on whether it is a first offense. Testing is done randomly throughout the season and for reasonable cause.

League spokesman Tim Frank declined to comment on the specifics of the case but said the NBA was monitoring the situation.
