The NFL is vehemently denying that there are any talks with CBS for the network to purchase a piece of the NFL Network.
Per ProFootball Talk:
Shortly after we posted an item on a report that CBS and the NFL were in talks for CBS to become a co-owner of NFL Network, we heard from the league office saying that the report is incorrect.
NFL spokesman Brian McCarthy told PFT the report is “Wrong. Not true.”
CBS is the largest NFL partner when it comes to broadcasting games. However, the NFL stands firm that the partnership will extend no further than that.
