The 29-year-old Khan will start as a massive underdog when he climbs into the ring to face the hard-hitting Alvarez at the gambling haven's sparkling new 20,000-seat T-Mobile Arena.
Khan, who normally fights at welterweight, is stepping up by two divisions to face Alvarez, a destructive puncher who has compiled an impressive 46-1 record with 32 knockouts.
The world title showdown is billed as a classic contrast of styles, pitting the elusiveness and speed of Khan (31-3, 19 knockouts) against the brute strength of the naturally bigger Alvarez.
"I'm seen as the underdog in this fight against Canelo but I feel this is the year of the underdog," Khan said after arriving in Las Vegas this week.

"What Leicester City achieved is absolutely amazing. You would have been called crazy if you thought that Leicester would win the title at the start of the season -- it's such an inspiring story.
"I'm definitely going to use that to help me. I'm ready to shock the world and beat Canelo. I know I'm ready for this fight and want to get in the ring right now."
"Initially I didn't like the fight. But I hadn't seen Amir. So when he came to camp I was surprised to see how much he had grown," Hunter said.
Khan's corner will hope the Briton's mesmerizing hand
speed will give him the advantage against Alvarez, whose only defeat came against another fighter with similar skills, the now retired Floyd Mayweather, in 2013.
The fight could hinge on whether Khan will be able to stick and move for 12 rounds while simultaneously avoiding Alvarez's heaviest body blows.
"I'm very happy with the work that I've done -- he's a very fast, elusive, tricky fighter. I know the work I've done and I'm confident I can go in there and break him down," Alvarez said.
"He will be surprised. Many think it's just about my power but when they get in the ring they realise that's not all there is."
Alvarez's trainer Chepo Reynoso acknowledged Khan's trademark speed. "Yes, he's fast -- but Saul also is not a turtle," Reynoso warned.
