Nearly a year after emerging from bankruptcy, regional sports network operator Main Street Sports is once again teetering on the brink of financial calamity. The company is in advanced talks on a deal to sell itself to DAZN, the London-based sports streamer. If an agreement for DAZN to take majority control does not happen by January, however, Main Street Sports is planning to shut itself down entirely, industry sources said. Such a move would revert the local rights of nine Major League Baseball teams, 13 in the NBA, and seven in the NHL back to those respective leagues and franchises. Resolution on the future path of Main Street Sports is expected by early January. MLB’s Cardinals did not receive a scheduled December rights payment from Main Street Sports, and there is a chance that several other teams, particularly in the NBA, could suffer the same fate in the coming weeks. St. Louis, however, has not terminated its rights agreement.
