You can watch UFC PPV live stream through ESPN+ pay per view. Here is everything you need to know more about how to watch all upcoming UFC PPV events on ESPN+, how much does it cost, how to order, why do I need it, does it free, can I watch other sports on ESPN and more. People need ESPN+ because it is far more affordable than ordering the fights from the cable. That was the initial way of watching the matches.
Unfortunately, you won’t be able to watch UFC 252 in the BT Sport. Perhaps you haven’t known this yet; the BT spokesperson confirmed that BT company would end the relationship with the UFC on December 3rd. That means BT Sports will no longer broadcast the UFC events on the channel. The UFC 252 event happens on Saturday, 15 August, 2020. But you can still purchase the PPV through the service.
