From TMZ.com:

UFC prez Dana White tells TMZ Sports … Brock Lesnar wants to RETURN to the Octogon … and White says he’d LOVE to have him back.

Dana was in NYC today getting ready for UFC’s Super Saturday … and told us Brock’s still bummed his fighting career ended short due to injury … and says “he’d like to take another run” in the UFC.

The former UFC heavyweight champ left the world of MMA in 2011 … after a string of losses that he chalked up to his battle with a potentially life threatening case of diverticulitis (a digestive disease).

Lesnar recently returned to the WWE … but White says that doesn’t mean UFC is off the table — “I think he wants to do both. When his schedule opens up I think he’d like to fight.”
