If featherweight champion Jose Aldo felt any anxiety over defending his title in Brazil for the first time as that nation's lone reigning lineal titleholder, he showed no sign of it Friday during the UFC 163 weigh-ins.
Aldo trotted toward the scale in Rio de Janeiro looking confident before weighing in at 145 pounds, making his Saturday night title bout against Chan Sung Jung official. Minutes earlier, Jung also weighed in at 145 pounds.
"I feel more confident because of the [Brazil-based] crowd," Aldo said after his customary stare-down with Jung. "The crowd pushes me to go forward all the time.
"I don't care much about what he's doing, I only care about myself. I'm in my house; I'm home; I can't be beaten here."
Jung, who is the underdog, also expressed confidence that he will leave Brazil with the belt.
"No matter what people might think, I am confident in my ability to win," Jung said.
Flyweight John Lineker weighed three pounds over the mandatory 126-pound nontitle limit. His opponent Jose Tome weighed 126.
Aldo, a Brazil native, makes the fifth defense of his UFC 145-pound belt. He became Brazil's lone current reigning UFC lineal titleholder on July 6 when Anderson Silva lost his middleweight crown to Chris Weidman.
Interim bantamweight champion Renan Barao also is a native of Brazil. Dominic Cruz, who has not competed since October 2011 due to injury, is the lineal UFC bantamweight titleholder.
