Members of the state gaming commission are raising red flags about the connections between the owners of Plainridge Park Casino in Plainville, which is applying for a sports betting license, and Barstool Sports.

Massachusetts lawmakers approved legislation to legalize sports betting earlier this year, and regulators hope to make such betting a reality at the state’s three casinos before the Super Bowl next February. Other options, including mobile sports betting, could come in the weeks and months after.

But at a meeting of the commission on Tuesday, members of the commission questioned representatives of Penn Entertainment, the parent company of Plainridge Park, about its relationship with Barstool Sports to help promote sports betting.
