-The latest news on Brock Lesnar is that his contract with WWE expires roughly one year from now in 2020. Reports claim that Lesnar could use UFC, and at the time his current deal is done, AEW as leverage to resign yet again, especially if AEW ratings are higher than expected. Although there is no guarantee that UFC is interested, as president Dana White stated that Lesnar had retired.
During their tour throughout the U.K. in November, WWE canceled shows in Nottingham, Birmingham, Minehead, and London. This occurred right around press time, with speculation being that the added pay per view in Saudi Arabia (Crown Jewel) changed the normal routine of the tour. Apparently future schedules will be adjusted to fit those normal stops, and Saudi Arabia in.
