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."
