UFC 155: Main Card Preview and Predictions

UFC Heavyweight champion Junior Dos Santos squares off against Cain Velasquez Saturday night at the MGM Grand Garden Arena in Las Vegas.

It will be Dos Santos’ second title defense, since he knocked out Velasquez for the belt in just over one minute in November of last year. It was Velasquez’s first defeat after he started his UFC career with nine straight victories, including a TKO of American Brock Lesnar.

Since making his debut in 2008, Dos Santos has earned a reputation as a devastating puncher, as evidenced by his quick knockout of Velasquez, and his 11 career KOs.

At 28, the Brazilian native is well ware of his strengths and his opponent’s weaknesses, practically guaranteeing another knockout.

"Cain is good standing too, but I can see holes during a fight better than he can, and I will be waiting for that opportunity," Dos Santos said to the Los Angeles Times. "It doesn't matter how prepared he is. I'm going to hit his face with good punches and I will knock him out."

The 30-year-old Velasquez earned his title shot by dropping the legendary Antonio Silva with a technical knockout in May.

The live event will start at 7 p.m. EDT, and if you can’t purchase the PPV at out home there are several ways to watch undercards and the main event live by going to UFC’s main website.
