The current UFC Heavyweight champion Brock Lesnar made his first TV interview since falling ill towards the end of last year, appearing on ESPN SportsCenter.

Lesnar said that he was diagnosed with diverticulous - a hole in the stomach - after he was originally diagnosed with mononucleosis.

Lesnar was put on medication as he didn't want to have surgery which would have resulted in the end of his fighting career. However a second opinion from the world-famous Mayo Clinic suggested that he should have his colon removed, a surgery that he avoided the first time around.

This month - after losing a total of 40 pounds - Lesnar gained back 30 of those through hard training in the gym and went back to see his doctors who couldn't find any problems with his stomach anymore.

The UFC champ, along with his doctors, couldn't believe it so they scheduled another CT scan to confirm the original findings with the results being negative again.

Dana White, who was also on the show, said that Lesnar will be back in the Octagon this Summer to unify the Heavyweight belt again after Frank Mir and Shane Carwin will battle out to see who will be crowned the interim champion.
