Young, talented, undefeated Julio Cesar Chavez Jr., son of the legend J.C. Chavez, will shake out in the big ring today -- Wednesday, Feb. 15 -- at The Aladdin Hotel-Casino in Las Vegas. Chavez Jr. of Culiacan, Mexico will be in the Aladdin ring beginning at noontime today. He is in a big rematch on Saturday night, taking on Carlos Molina on Top Rank's "Real Warriors" Pay Per View card at The Aladdin. Chavez Jr. and Molina battled to a draw two months ago in Mexico. As a result, Julio Jr.'s father sent his son to train at The Otomi in the mountains of Mexico. "When I was young child I used to go with my father while he trained for the big fights," said Chavez Jr. "It's so beautiful in the mountains - so many things to see. "Now, he told me, it is my turn to train there and become the best I can be."
