Boxing rising star Ryan Garcia says he's completely SHOCKED legends like Oscar De La Hoya and Mike Tyson making a comeback ... telling TMZ Sports those guys are straight-up "nuts!!!"
54-year-old Mike and 51-year-old Roy Jones Jr. are dusting off the cobwebs and facing off on Nov. 28 ... which seemingly started a trend.
We spoke with King Ry out in L.A. and since he's signed with Oscar's Golden Boy Promotions -- we wanted to know how he felt about ODLH getting back in the ring at 47-years-old.
"Aw man, Oscar, shoot. Let him do whatever he wants!" Garcia tells us ... adding, "If Mike did it, why not?"
Oscar does NOT have an opponent lined up yet but insists he's still got the skills to beat a real opponent in the ring.
So, how does Ryan feel about comeback season?!
"They're nuts, that's what I'm saying. They're nuts! I can't believe it."
There's a bunch more with undefeated 22-year-old Ryan -- he gives an update on his wishlist of upcoming opponents from Tank Davis to Henry Cejudo ... and also weighs in on his recent training sesh with TikTok stars Dixie D'Amelio and Addison Rae!!
