I got the email from Xfinity (Comcast) this morning in my email. I subscribe to MLB Extra Innings through Xfinity so Bally Sports is affected . Here is a list of teams affected :
DSG owns and operates 14 Bally Sports RSN channels nationwide, including:
Bally Sports Detroit — Airing games from the Detroit Tigers, Detroit Red Wings, and Detroit Pistons
Bally Sports Florida — Airing games from the Miami Marlins, Florida Panthers, and Orlando Magic
Bally Sports Hybrid (IN) — Airing games from the Cincinnati Reds, Detroit Tigers, Columbus Blue Jackets, Indiana Pacers, and Detroit Pistons
Bally Sports Midwest MO — Airing games from the Kansas City Royals and St. Louis Blues
Bally Sports Midwest — Airing games from the St. Louis Cardinals, Kansas City Royals, St. Louis Blues, Indiana Pacers, and Memphis Grizzlies

It appears nine major league teams are affected. Since I have Extra Innings I should be able to watch their games if they are playing a team that's not affected. For instance, Atlanta vs Dodgers is on LADX on Mlb Extra Innings but I will still miss several games.
