The UFC’s popular “Primetime” series will return this fall and winter with regularity. Sources close to the promotion told MMAjunkie.com (www.mmajunkie.com) that the UFC is planning to produce “UFC Primetime” shows for its final three pay-per-view cards of the year – UFC 166, UFC 167 and UFC 168. No formal announcement from the UFC has come yet for any of the three, but with the transition next month to FOX Sports 1 as its primary cable home, that new network is expected to broadcast the episodes. Broadcast dates and times are not yet known.
