Jim Irsay was arrested late Sunday night on preliminary charges of driving while intoxicated and possession of a controlled substance.

Irsay tweeted on Oct. 21, 2013, that he hadn't had a drink in more than 15 years. He admitted in a statement in 2002 that he had an addiction to pain killers.

“There are people around the Colts organization who have been suspicious about some of his behavior,” Adam Schefter said Monday morning onSportsCenter.

Irsay has previously acknowledged his struggles with addiction.

Irsay will be subject to discipline from Roger Goodell.

“He’s a sick, sick man,” one source told Bob Kravitz of the Indianapolis Star. “He desperately needs help.” 

Irsay had lost 70 pounds down to 165.
