Brock Lesnar - Great Balls of Fire WWE 2017

Stunner emerges on the rumored WWE future of Brock Lesnar

WOAH!

Brock Lesnar remains one of WWE's biggest stars despite a part-time schedule. Although he's likely raking in cash after headlining last year's WrestleMania, Lesnar is reportedly considering a jump back into MMA and has re-entered the USADA cycle required for drug testing ahead of fighting professionally.

With that comes the stunner that he's considering not re-signing with WWE when his contract expires following WrestleMania 34, per Pro Wrestling Sheet.

"Sources tell us Brock's contract with WWE expires not long after WrestleMania 34 next year and he's already made it clear to backstage officials that he currently doesn't intend to re-sign."

Obviously things can change, but this is a rough look for WWE currently void of huge superstars.

Lesnar originally beat Mark Hunt in his UFC return in July 2016, but it was overturned thanks to a failed drug test. He lost his previous two bouts at the hands of Cain Velasquez and Alistair Overeem, via TKO.

Plans in WWE rapidly change, but according to Cageside Seats, current backstage plans are set in place for John Cena to challenge the holder of the Universal championship at WrestleMania 34 for the belt.

Wrestling Observer previously noted the long-term plan was to build Roman Reigns over the next year and have him take the belt from Brock Lesnar at WrestleMania 34 in New Orleans. It would be a rematch from WrestleMania 31, where Seth Rollins cashed in his Money in the Bank briefcase to win the title.

Those plans have apparently changed, as the original idea was for Lesnar to bide his time in a program with Braun Strowman. Reigns is slated to face Samoa Joe on Monday night for the No. 1 contender spot.

According to the report, Cena will match up against whoever has the belt — Reigns or Lesnar.

Cena was on the Smackdown brand, but recently became a free agent and is allowed to show up on either shot.

Lesnar is currently 40 years old.
