Ireland viewers can tune in the Eleven Sports. As mentioned, BT Sport will no longer provide the service starting from December 3rd. You will want to purchase the PPV through the UFC.tv for a safer and more comfortable option. If you already have the UFC FIGHT PASS, the process will be much easier. Not to mention that you can also watch Preliminary Fights live stream for free by using your FIGHT PASS credentials.
UFC 252 is the upcoming PPV event. In this case, PPV is the only official way that you can take to watch UFC 252 without any problem. The preliminary fights will be available in UFC Fight Pass, FOX Sports, as well as ESPN. If you have subscribed to either of them, you will be able to watch the preliminary fights for free. However, you will need to purchase the PPV package through UFC.tv to attend the main event of the UFC 252. If you are a subscriber of the UFC.tv, you can watch the UFC 252 main event replay a month after the actual event happens.
