For Urijah Faber, age really is just a number. Even at 40 years old. 

Faber (35-10-0) was back in the octagon for the first time since retiring in December 2016 and only needed 46 seconds to beat 26-year-old Ricky Simon (15-2-0) on Saturday at Golden 1 Center in the co-main event at UFC Fight Sacramento. "The California Kid" hammered Simon with a right-hand jab and then it was off to the races for the hometown hero.

Faber, a +260 underdog by Caesar's Palace, earned his first win by knockout since 2007. The 46-second victory was the fastest in his UFC career. He now has the second-most bantamweight wins in UFC history. 

At 46 seconds, @UrijahFaber earns the fastest finish of his entire career.

"I love fighting for Sacramento," Faber said after his win. "Props to Ricky Simon. That kid is gonna be a terror in this weight class. He has the right mentality, but he's just not there yet. It takes time, baby. Experience." 

Faber, a world-class wrestler, said he learned the right-hand jab from Song Yadong, a Chinese prophet who trains out of Team Alpha Male. 

"He [Simon] had a big target there, not to be mean," Faber said. "I was like, 'I'm gonna hit this dude's head, for sure.'" 

It doesn't sound like he's done, too. Faber called out Henry Cejudo and has his eyes on the bantamweight belt.

"I gotta get it now, before it's too late," Faber said about going for the championship belt.

Faber proved he's plenty capable of still fighting at 40 years old, and he could have more in his future. 

When Daniel Cormier enters the Octagon on Saturday to face Stipe Miocic in their much-anticipated rematch at UFC 241, he'll be fighting for more than just his chance to retain the heavyweight belt.

Cormier, who trains at American Kickboxing Academy in San Jose, also is the wrestling coach at Gilroy High School. Tragedy recently hit the Gilroy community when a gunman opened fire at the Gilroy Garlic Festival on July 28, killing four people and wounding 13 others.

So Cormier not only will be fighting for the belt Saturday at Honda Center in Anaheim, but also to represent his community.

"With my attachment to the community, and being the guy that's probably -- you know I talk about all the fighters from the city, but I'm the guy at the forefront as the champion," Cormier told NBC Sports Bay Area. "The opportunity to represent the community on such a massive stage is a huge honor for me. It hasn't been long since the shooting happened, and to be in such a big spot and to carry the flag of the town of Gilroy means a ton to me. 

"People will be watching. They will be rooting and cheering. I know that on Saturday, I'm going to show and prove how strong people from Gilroy are and make them proud."

Cormier defeated Miocic via first-round knockout at UFC 226 last July,

He hopes to lift a belt and a community Saturday with another victory over Miocic on Saturday.

The eyes of the UFC world are locked on UFC 241 and Daniel Cormier's rematch with Stipe Miocic.

Cormier vs. Miocic 2 will take place Saturday at Honda Center in Anaheim, but as is commonplace in UFC, Conor McGregor stole the spotlight Thursday.

TMZ published a video of McGregor punching an elderly man in the head at a Dublin bar back on April 6. 

McGregor reportedly was buying shots of his Proper 12 whiskey for the bar patrons, and the man refused twice, leading to the strike. 

As often happens when McGregor makes news, Cormier was asked about his reaction to the incident. Cormier, who trains at American Kickboxing Academy in San Jose, offered his support and some advice to the UFC megastar. 

"Part of me doesn't even want to watch it, you know," Cormier told NBC Sports Bay Area. "I don't want to see a kid in Conor, he just has the world at his fingertips -- if this is true, I think it's time for the people in his life that really love him and care for him to just sit him down and have a conversation. Again, there's been a number of occasions where things seem to be going in the wrong direction. Sit him down and just kind of reel him in.

"Conor is a great guy," Cormier continued. "I spent time with him, he's a really, really good guy. He just needs to remember, it's not just him anymore. It's his kids, his wife and a legion of people that look up to him."

UFC president Dana White told TMZ that a lot of people get punched in Irish bars all the time, but McGregor still can't go around punching people.

There has been no legal action yet, and time will tell if the UFC and White take action.

As for Cormier, he beat Miocic via first-round knockout at UFC 226 last July and now hopes to defend his title in Anaheim.
