As fans eagerly await the WWE Heavyweight Championship fight between John Cena and Brock Lesnar, the current champion and former UFC heavyweight champion, Lesnar, is considering going back to UFC, Mixed Martial Arts.

According to the latest addition of the Wrestling Observer Newsletter, Lesnar's current bosses at WWE are operating under the assumption that the 37-year-old will return to the UFC when his contract expires in March 2015. (via MMAjunkie)

"The Lesnar people always keep things quiet, but within the company, the belief is that he's going back to UFC, and his showing up lighter to TV last week confirmed that to people who thought it," the report stated.

While UFC president Dana White has previously suggested he will be willing to consider Lesnar's return to the promotion, when reached for comment, the exec said there hasn't been any progress on that front.

"I haven't talked to Brock," White told MMAjunkie via text.

In November, at the UFC's "The Time is Now" press conference, White admitted that Lesnar has expressed a desire to compete in UFC again.

"We have a great relationship with him," White said of Lesnar. "He's healthy, and he's said that he's interested in fighting again. We'll see what happens."

On the WWE front, the Royal Rumble match between Lesnar and Cena will take place in early 2015 and rumours suggest that the two will face each other again in WrestleMania 31 before Lesnar's contract expires.
