Roy Nelson made sure to let Shane Carwin know what he was in for in the build-up to their planned fight.

Now, with Carwin out and Matt Mitrione in for this Saturday night at The Ultimate Fighter 16 Finale, “Big Country” has even more of a personal stake in the action.

“Matt actually asked for this fight, so it’s more personal,” said Nelson, during a recent conference call.

Nelson (17-7) is coming off a victory over Dave Herman, but has alternated wins and losses in each of his previous four fights. He said the biggest difference between Carwin and Mitrione is their style.

Nelson and Mitrione were castmates on The Ultimate Fighter. Nelson went on to win the season, defeating Brendan Schaub in the finals.
