BOSTON (AP) — Three companies seeking to develop a resort casino in Springfield submitted applications Thursday to the western Massachusetts city, and a fourth that had previously expressed interest declined to enter the competition.

Penn National Gaming, which unveiled details of an $807 million casino plan earlier in the day, MGM International and Ameristar Casinos met the Thursday 5 p.m. application deadline set by city officials, who are expected to select one proposal to put before voters.
