Four Pacers were involved in the mayhem at Club Rio early Friday. Police said Jackson fired a gun in the air in apparent self-defense and was struck by a car that sent him tumbling onto the hood.
Coach Rick Carlisle said Saturday that Jackson and teammates Jamaal Tinsley, Marquis Daniels and Jimmie Hunter committed an "error in judgment" by staying out late during training camp but he was relieved no one was seriously injured.
Police said they found a small amount of marijuana in the passenger-side door of point guard Tinsley's car. But no arrests were made because there were three others in Tinsley's car and police could not determine who had the marijuana, authorities said.
Jackson was expected at Pacers practice Tuesday for the first time since the fight.
