The 39-year-old Smith (29-8, 12 KOs) won his world championship with a majority decision over Cornelius Bundrage on Feb. 23, 2013 to become the first Las Vegas-native to win a world title. He has also challenged top fighters such as Erislandy Lara and Daniel Jacobs and most recently defeated Tommy Rainone and Frank Galarza in his last two bouts.

"I took this fight just like I've taken every tough fight over the years," said Smith. "I constantly challenge myself to the best and I believe Julian Williams is one of the best in the division. If you look at my resume, all I've done is fight the best guys, in their prime, so this is nothing new to me. I've reached the point where I've seen it all. This fight will get me exactly where I need to be, closer to a world title shot."

Williams (23-1-1, 15 KOs), one of the top young contenders in the 154-pound division, is working his way back into title contention by taking on a tough former world champion in Smith. The 27-year-old Williams of Philadelphia suffered a KO loss to Jermall Charlo in his first title shot in 2016 and returned to the ring with a TKO victory over Joshua Conley in his last fight on June 30.

"We've been working hard for months and I'm ready to get back in the ring," said Williams. "I could fight tomorrow. I know this is an important fight for my career. Ishe is a veteran and he is going to bring his 'A' game to try to prove he's still got it. I'm not going to give him that opportunity. I will be victorious and show that I'm ready to fight the best in the world."

Lionell Thompson (18-4, 11 KOs) is on the trail of a 175-pound world championship and he hasn't taken the easy road, having challenge the likes of Sergey Kovalev and Radivoje Kalajdzic in his pro career. The 32-year-old out of Buffalo, N.Y. is coming off a knockout victory over Steve Lovett in his last fight on Feb. 24. The last time he fought at the Cosmopolitan, he defeated Donovan George by unanimous decision on Sept. 16, 2016.

Unbeaten prospect Earl Newman (10-0-1, 7 KOs) will be taking a big step forward in taking on his toughest competition to date in Thompson. The 26-year-old Brooklyn-native is coming off a split draw against Paul Parker on Sept. 19 after winning his first 10 pro fights.

A 2012 Olympic Silver medalist from Mongolia, Tugstsogt Nyambayar (8-0, 8 KOs) now fights out of Carson, California. The 25-year-old turned pro in March of 2015 with a first round knockout of Gabriel Braxton. Since then, Nyambayar has stopped every opponent in his path, including most recently scoring a 10th round TKO over Jhon Gemino in February.

The unbeaten 19-year-old prospect Xavier Martinez (9-0, 5 KOs) will face his toughest test as a pro when he enters the ring on November 18. Representing Sacramento, Martinez has scored two victories in 2017 having stopped Jesus Aguinaga in September after earning a decision over then unbeaten Prince Smalls in June.
