#2 Brock Lesnar's last match?

As has been strongly speculated, it appears that Brock Lesnar's match against Roman Reigns this Sunday at WrestleMania will be his last.
Lesnar's contract with the WWE is set to expire after WrestleMania 34 and a return to UFC has been teased. It has been reported that WWE won't permit Lesnar to fight with the UFC whilst under contract, however, Lesnar did compete at UFC 200 whilst on the WWE's payroll.
It is still uncertain whether or not Lesnar will return to the UFC given his previous problems there, first being his failed drugs test which led to his victory at UFC 200 being overturned, and second, his bout with diverticulitis in 2011 which affected his ability to perform.
It could be said that WWE has deliberately misled their audience into believing that Lesnar is leaving, an example of this being Roman Reigns' promo a few weeks ago on Raw which fuelled the speculation about him leaving. This could be the WWE's way of getting the fans behind Reigns' who otherwise might have been very pro-Brock or just hyping the match in general.
Whether Lesnar will leave the WWE or if they are working the crowd in order to add fuel to their match is unclear at this stage, but there is no reason why Lesnar cannot continue to work his part-time schedule with WWE and fight another match with the UFC if he wanted. Lesnar is clearly a prized asset for WWE and one they have invested a lot of time into, so to let him go so easily would seem silly.
