The 24-year-old former LSU star and the No. 1 draft choice in 2007 was arrested as part of an undercover narcotics investigation, said Mobile County Sheriff's spokeswoman Lori Myles. She would not say what led to his arrest. She said he did not have a prescription for the codeine.

Myles told reporters that several people were in Russell's home at the time of his arrest but Russell was the only person taken into custody.

Russell has a bond hearing scheduled for Wednesday and is due back in court on July 20.

"We understand that typically sometime this codeine syrup is mixed with a beverage, like Sprite, and they call it sip-sip," Myles told WALA-TV in Mobile.
