O.J. Simpson is heading back to jail after he allegedly violated the terms of his bail. According to court papers obtained by TMZ, Simpson called one of the co-defendants involved in his armed robery case.

Simpson — who was let out on $125,000 bail in September after he allegedly burst into a Las Vegas hotel room and robbed two sports memorabilia dealers at gunpoint — is due in court on Wednesday, Jan. 16 for a bail hearing.
