WWE superstar and former UFC heavyweight champion Brock Lesnar is interested in returning to mixed martial arts, UFC President Dana White said Monday. The 37-year-old wrestler last fought in the UFC in 2011.

“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. We’ll see what happens,” White said at a press conference, according to Fox Sports.

Lesnar first signed with the WWE in 2000 after a successful collegiate wrestling career. His contract with the professional wrestling organization runs through WrestleMania 31 on March 29, 2015. After that event, Lesnar would be free to sign with any organization, including the UFC. He is the only person in history to have won championships in the NCAA, WWE and UFC.

Lesnar defeated legendary MMA fighter Randy Couture to win the UFC Heavyweight Championship in just his fourth professional fight. He successfully defended the title twice, but suffered back-to-back losses to current champion Cain Velasquez and fellow heavyweight Alistair Overeem.  

He retired immediately after his fight with Overeem, citing health concerns which stemmed from his bout with diverticulitis. The digestive tract disease required multiple surgeries and nearly killed him, ESPN reported. Lesnar currently holds a 4-3 career record in the octagon.

WWE personality Paul Heyman said in August that Lesnar spent his entire UFC career fighting fighting below full capacity. “Anything you saw him do, he did as an unhealthy man competing at the very top level on the face of the planet. Imagine what he could have done if he was 100 percent healthy,” Heyman said.

This isn’t the first time that White has publicly addressed a former fighter’s return to mixed martial arts. The UFC has spent the last several months courting former Strikeforce champion Gina Carano, long rumored to be a potential opponent for undefeated UFC Women’s Bantamweight Champion Ronda Rousey.

"I don't know, we'll see how these things play out. Just incredibly difficult. We've dealt with (Brock) Lesnar, Tito (Ortiz), Chuck (Liddell) was f--king king of the world, Ronda Rousey, we've pretty much done deals with everyone on Earth and [Carano] is the hardest f--king athlete we have ever dealt with,” White said in September, according to Fox Sports.
