According to a report from the Wrestling Observer Newsletter, Brock Lesnar’s current status and future with WWE is being kept a very closely guarded secret. There are said to be only a “handful” of people who know, including Vince McMahon, Nick Khan, Triple H and possibly two others.
For what it’s worth, there have been rumors circulating that Lesnar is telling people that he’ll be leaving in the near future. When Lesnar left the last time, he put over Drew McIntyre at WrestleMania 35.
