"I don't know how the judges scored the last round. It could have been or should have been a 10-8 round. But that doesn't take anything away from Dan Henderson. He is a legend and those are the type of fights that create a legacy," said Rua.
Rua is looking forward to seeing a replay of the fight.
"I'm going to rest with my family now and take care of myself. Then I'm going to go back and look at the tapes. I want a rematch and I think this would be another great battle and one the fans would definitely want to see," said Rua.
FightMetric backed up Rua. The Brazilian outlanded Henderson 26-0 in significant strikes over the final minutes and 79-8 overall in the fifth.
John Morgan, 2009 MMA Journalist of the Year, scored it a draw as did Adam Hill from the Las Vegas Review-Journal. ESPN.com's Brett Okamoto scored it 48-46 for Rua.
Will Angland at Bleacher Report wrote a strong piece saying Rua was robbed.
