The UFC returns to Rio de Janeiro this weekend for UFC 224, and it stacked the card with plenty of star power for the local fans.

Amanda Nunes will make her third title defense, and we'll see two former Brazilian champions open the card. Brazilians tend to be favored in local events, so usually the question for gamblers is whether the juice is worth it or if there's a crowd-silencing upset in the works.
