Allen Iverson has been banned from both MGM and Greektown casinos in downtown Detroit, the

Detroit News

reported on its Pistons blog.

A regular casino visitor since he arrived in town, the blog said Iverson has been "banned mostly for his boorish behavior. He is a bad loser, and he loses a lot, often throwing his chips or cards at the dealer. He has been warned about improper behavior at the tables repeatedly. He is often loud and disruptive, according to witnesses, rude to dealers, other players and the wait staff."

The NBA is looking into an incident at Greektown that involved one of Iverson's bodyguards, the News said. It is unclear what Iverson's role was.

Iverson caused a disturbance at a casino outside Minneapolis earlier this season and had a long history in Atlantic City while he was with the 76ers.

In December 2005, Iverson got into an argument with a dealer at the Trump Taj Mahal casino after the dealer overpaid him $10,000 on a bet he made while playing three-card stud poker. Iverson initially refused to give the chips back but did so later and received a gaming voucher in that amount from the Taj.

In February 2004, Iverson urinated into a trashcan at Bally's on the casino floor, shocking nearby patrons. On several trips to Philadelphia, Iverson and his friends returned to the Taj Mahal, his Atlantic City spot of choice. *
