As noted, Brock Lesnar’s current WWE contract ends on the night after WrestleMania 31.
It is not confirmed that Brock Lesnar would NOT re-sign with WWE, but rumors circulate that Lesnar will likely try and make a return to UFC.
Backstage belief is that UFC may have the best shot at signing Lesnar because WWE may not be in a financial position to offer Lesnar a deal that he has had over the past three years from the company. Brock Lesnar could also use UFC as a negotiating tool to get more money from WWE.
