Some of the league's officials are holding a grudge against Stephen Jackson, according to his agent, Mark Stevens.

Stevens says he has noticed a pattern of calls going against Jackson.

NBA spokesman Tim Frank said the league has "no comment" about the agent's remarks.

Stevens said a non-call at the end of Charlotte's 104-103 loss to Indiana was the final straw.

"The inconsistency of the referees' calls or non-calls in close games is becoming questionable," he said. "It looks like they're taking the player and/or his personality into account when deciding whether or not to make calls."

Stevens believes Jackson, who has a reputation as a volatile player, is being singled out by officials.

"The referees are the law enforcement arm of the game," he said. "They enforce the rules and regulations that the players must abide by. However, just as profiling is wrong in police work, we must make sure that the league does not do personal profiling of certain players.

"I understand that my player has had past conflicts with the referees, but their job is to be as fair as possible when calling the game, regardless of any past issues with a player."
