A Suffolk Downs casino in East Boston is still a possibly — it just won’t be Caesars.

Caesars Entertainment, a household name in the gaming industry, has been dropped from consideration for a proposed casino at Suffolk Downs after growing concern that Caesars would not pass a mandatory state background check, according Boston.com.

Still, hoping to land the sole Greater Boston casino license, Suffolk Downs’ ownership will look to replace Caesars with another casino.

East Boston and Revere residents will vote Nov. 5 on the casino proposal.

Questions were raised after state casino investigators grew weary of a possible business relationship between Caesars and a person alleged to have family members tied to organized crime outside the US, people familiar with the investigation report told the Globe.

A public hearing –two weeks from now– for Suffolk Downs will make these findings public.

Suffolk Downs reportedly remains confident it will be “deemed suitable to bid for a license.”

Caesars withdrew from consideration Friday night.

“We believe that the Gaming Commission is attempting to set suitability requirements that are arbitrary, unreasonable, and inconsistent with those that exist in every other jurisdiction,” a spokesman with Caesars told the Globe.

Mayor Tom Menino signed a host agreement with Suffolk Downs that would provide the city with at least $32 million annually. Caesars was “in small part,” included in the agreement, the mayor’s spokeswoman Dot Joyce told the Globe.

Wynn Resorts proposal in Everett and a Foxwoods project in Milford are competing with Suffolk Downs for the area’s casino license. A winner is expected to be chosen in early 2014.

To date, five casinos have passed background checks: Penn National Gaming, Cordish Cos., Raynham Park and partner Greenwood Racing, Mohegan Sun, and Rush Street Gaming — who is no longer active.
