Khabib Nurmagomedov and Justin Gaethje both made weight Friday ahead of their lightweight championship unification bout in the main event of UFC 254 on Saturday.
ESPN's Marc Raimondi reported Khabib weighed in naked and appeared to breathe a sigh of relief after the scale showed 155 pounds.
Nurmagomedov hasn't fought since September 2019, when he defeated Dustin Poirier by third-round submission. He was scheduled to face off with Tony Ferguson in April, but that bout was canceled because of coronavirus pandemic-related travel restrictions.
Ferguson instead battled Gaethje for the interim belt, and the latter emerged victorious by fifth-round knockout to set up Saturday's clash with Khabib.
The 31-year-old American said he will likely need to make it an "ugly" fight to score the upset.
"We are absolutely more focused on grappling and stopping the grappling," Gaethje told reporters Thursday. "Causing scrambles, getting up if I get taken down. But ultimately, it's causing damage in between those instances. I need to cause damage. I've got dense bones, and when I hit people, it tends to hurt 'em. So I need to kick him, I need to hit him and I need to make it ugly."
Khabib has reiterated throughout his preparations that he's going to keep trying to grapple, even if the former NCAA wrestler successfully defends his initial attempts.
"I'm going to try wrestling with him," Nurmagomedov said. "If he's going to defend my takedown one time, I'm going to try second, third, going to try 100 times and, of course, I'm going to box with him, gonna kick with him, you know."
While Gaethje has rightfully spent a lot of time preparing for those grapple situations, the key may be whether he's able to mount enough offense. If he spends the entire fight in a defensive shell, Khabib will easily be able to outpoint him on the scorecards in a fight that fails to meet the hype.
So he must capitalize on counterattacking opportunities, especially in the first few rounds in an effort to start wearing down his Russian opponent, who's fighting for the first time in nearly 14 months.
The main card of UFC 254 is scheduled to start at 2 p.m. ET on Saturday from UFC's Fight Island in Abu Dhabi in the United Arab Emirates.
