Diamond Sports, the parent company of Bally Sports Regional Networks, has filed for bankruptcy protection. This move could potentially have far-reaching consequences for sports fans, who may see changes to the availability of regional sports coverage.

According to ESPN, Diamond is the owner of RSNs for over 40 teams, while CNBC reports that it is the largest owner of regional sports networks in the country. The filing for bankruptcy protection follows a difficult period for Diamond, which has struggled with declining revenues and rising costs.

Fans may be particularly concerned about the potential impact on Bally Sports, which provides coverage of many popular sports teams across the country. The Athletic suggests that this could be a “RSN armageddon,” with many teams potentially losing coverage altogether.

However, it is not yet clear exactly what the impact of the bankruptcy filing will be. MLB Trade Rumors notes that Diamond has stated that it intends to continue operating its business as usual during the bankruptcy process.

For now, fans will have to wait and see exactly what this means for their favorite teams and sports.
