21-year-old Steveson was one of the breakout stars at the 2020 Olympics ... and has expressed interest in everything from the NFL, to WWE, to the UFC.

So, we asked the UFC prez if he had interest in Steveson ... and that's when White revealed he planned to link up with the gold medalist.

"[Gable] will be in town this weekend, and I think we're gonna hook up and talk."

Steveson -- who recently got an offer to train from WWE superstar Seth Rollins -- is gonna be in Sin City for SummerSlam.

FYI, Gable is a BEAST on the mats. He won the NCAA title this year at the University of Minnesota, as well as the championship at the Pan American Games. Gable hasn't lost a single match in 2 years.

But, just 'cause Dana's meeting Gable, doesn't mean a signing is guaranteed.

"Obviously there's a lot of work for him to do before he could make it to the UFC, but we'll see what happens."

If Steveson does ultimately sign a deal with the UFC ... fellow Olympic gold medalist turned UFC double champ Henry Cejudo recently told us he believes Gable -- with 2 or 3 years training -- could beat top heavyweights like Jon Jones and Francis Ngannou.

Either of those fights would be HUGE. But, first step is White and Steveson's Vegas meeting.
