A gambling company looking to develop a resort at the Brockton Fairgrounds has applied for the final casino license in Massachusetts.

A spokeswoman for Mass Gaming & Entertainment, an affiliate of Chicago-based Rush Street Gaming, confirmed that an initial application was filed before Friday's 5 p.m. deadline. The company declined to release the application materials or more information about the project.

George Carney, owner of the Brockton Fairgrounds, said the operators of Philadelphia's Sugar House casino, among other properties, are eying his facility. Mass Gaming & Entertainment initially sought a slot parlor license for a development in Millbury, but eventually dropped that plan in the face of local opposition.

The final license is designated for the southeastern portion of the state that includes Fall River, New Bedford and Cape Cod.

K-G Urban Enterprises has already filed its application to construct a waterfront casino in New Bedford.
