UFC star Urijah Faber's comeback could be a short one -- like 1 fight -- IF he doesn't get a crack at champ-champ Henry Cejudo, the HOFer tells TMZ Sports.
40-year-old Faber walked away from fighting in December 2016 ... but recently inked a deal to fight Ricky Simon at UFC Fight Night 155 on Saturday -- almost 3 years after retiring.
The California Kid tells us he hasn't decided what he'll do after his fight -- meaning he could hang the gloves back up.
"The truth is, I'll make that decision later. I'm really enjoying this process at the moment. For me, 1 fight at a time," Faber tells us.
But, there's 1 big catch ... he'll absolutely without any doubt fight Cejudo.
"Fighting Henry Cejudo, Mr. Cringe himself," Urijah says ... "I'll fight that dude all day. Believe that."
Remember, Henry called out Urijah in the Octagon after winning the bantamweight title last month.... saying he had a hit list and Faber was on it.
"Styles make matchups. He's not gonna break me, that's absolutely sure. I'm not worried about getting out wrestled or out grappled. His pressure is what's won him fights. That's something I can handle. Pressure is all good with me."
Faber also went at UFC honcho Dana White ... who recently said he was too old to fight Cejudo.
