Suits were filed on Monday against the Indiana Pacers and players Jermaine O'Neal and Anthony Johnson by a Detroit fan who was trespassing on the court.

O'Neal and Johnson already face assault and battery charges for allegedly attacking Charles Haddad during the Nov. 19 fight between Pistons fans and Pacers players. The charges carry up to 93 days in jail and a $500 fine.

The suit was filed in U.S. District Court by Haddad, a 21-year-old Pistons season-ticket holder. Prosecutors charged him with violating an Auburn Hills ordinance barring fans from the court. He could get up to 90 days in jail and a $500 fine.

In his suit, Haddad said Indiana's Ron Artest knocked him down while fighting with another fan.

"Before he could get up, and while he was still face-down, (Haddad) was jumped upon by ... Johnson and pounded repeatedly in the back of his neck, head (and) kidneys," the suit said.

While Haddad was being helped to his feet, "O'Neal came running from middle court ... and struck him barehanded with a windup punch" in the face, the suit said.
