WWE World Heavyweight Champion Brock Lesnar may have returned to Monday Night RAW this week to fulfill his current contract, but the negotiations with Vince McMahon on his next pact have continued to hit a wall.

Lesnar stormed out on RAW two weeks ago after he had an argument with McMahon over the negotiations of his next deal, but he was back on RAW to help build up his WrestleMania 31 match with Roman Reigns.

Lesnar and his manager Paul Heyman were booked for a segment with Reigns on the Feb. 23 RAW in Nashville, but after Lesnar stormed out, Heyman and Reigns did a segment without "The Beast."

This week, Lesnar returned, but things are said to still be bad between the WWE World Heavyweight Champion and McMahon.

According to Wrestlingheadlines.com, despite Lesnar being at RAW, things between him and McMahon haven't changed and they are still unable to resolve their issues.

The situation is described as one where neither man wants to back down from what they want and Lesnar and McMahon have hit an impasse in their negotiations.

It's likely that nothing will come of a new contract until one of them backs down. It is expected that Lesnar's deal runs through the March 30 edition of RAW on the night after WrestleMania, so there could be a gap between deals for him.

There were rumors that Lesnar might want to return to UFC after retiring from the Octagon in 2011 due to a bout with diverticulitis. Lesnar, a former UFC Heavyweight Champion, has a good standing relationship with UFC president Dana White.

There was some speculation that a three-way bidding war between the WWE, UFC and Bellator MMA for Lesnar's services may emerge, however with "The Beast" already negotiating with the WWE, it seems as though his mind is made up.

Lesnar has had a dominant year in the WWE, ending The Streak of The Undertaker at WrestleMania XXX last year and then dominating John Cena to win the WWE World Heavyweight Championship at SummerSlam in August while looking strong up to this day.

It is expected that Lesnar will drop the title to Reigns at WrestleMania 31 on March 29 at Levi's Stadium in Santa Clara, Calif.

What happens with "The Beast" after his contract expires remains to be seen.
