New England’s last remaining thoroughbred horse racing track might continue to hold live races after all. Months after its owners said they would stop hosting races after the 2014 season, Suffolk Downs and the New England Horsemen’s Benevolent and Protective Association announced Friday that they’ve reached an agreement to hold races in 2015 and 2016. The deal would allow the association to lease the track from Sterling Suffolk Racecourse LLC. But the deal is contingent on state lawmakers approving enabling legislation. The state Gaming Commission also needs to approve the arrangement. Sterling Suffolk Racecourse hosted its last races in October, shortly after Mohegan Sun lost its bid for a casino license to build a resort on the property.
