The arrest of JaMarcus Russell for alleged possession of codeine syrup resulted from a two-month undercover investigation that could result in more arrests.
Mobile County Sheriff's Office spokeswoman Lori Myles said Tuesday that the investigation wasn't targeting the former Oakland Raiders quarterback but that his name and home address had come up several times.
The 2007 No. 1 draft choice was arrested Monday at his home and charged with possession of a controlled substance. Myles says forensic tests to determine the amount of codeine syrup involved sometimes take 5-7 days
Russell has a bond hearing Wednesday and his trial is scheduled for July 20.
Russell did not return a call from The Associated Press Tuesday. A business partner of Russell's agent said they had no comment.
