WWE World Heavyweight champion Brock Lesnar is seemingly in a state of flux entering WrestleMania 31, but a new report suggests that The Beast Incarnate could remain with WWE over the long haul.

There has been plenty of speculation regarding the possibility of Lesnar returning to UFC once his WWE contract expires following WrestleMania, but former announcer and WWE Hall of Famer Jim Ross revealed in a blog post that he is hearing that the former UFC Heavyweight champ may ultimately decide to stick with wrestling due to concussion concerns.

Sources are saying that it looks more promising that Brock Lesnar could well stay with WWE past WrestleMania due to concerns over long-term health effects of competing in MMA, specifically concussion-oriented issues later in one's life. Again, these are 'sources' and how reliable they are can only be judged after WM31 and following the status of the former UFC Heavyweight champion.

JR's revelation is a far cry from what many have long assumed regarding Lesnar's future. It was just a few months ago, in fact, that UFC president Dana White discussed the 37-year-old star's desire to return to the octagon, according to Damon Martin of FoxSports.com.

"Brock Lesnar's under contract with the WWE. We have a great relationship with him. He's healthy and he has said that he's interested in fighting again," White stated. "We'll see what happens."

Lesnar is currently slated to main event WrestleMania against the winner of the match between Roman Reigns and Daniel Bryan at Fastlane.

His match promises to be of great interest no matter what, but the possibility of remaining with WWE certainly makes it that much bigger since retaining the title would suddenly be on the table.

Lesnar is a hot commodity with the option of doing essentially whatever he pleases when his WWE contract is up, but he seems to have a great arrangement in place, and it is easy to understand why he might consider maintaining the status quo.
