At UFC 146, Roy Nelson (16-7; 3-3 UFC) meets Dave Herman (21-3; 1-1 UFC). This is the third fight on the all Heavyweight main PPV card. Nelson is currently the #15 Heavyweight in the world according to the USA TODAY / MMA Nation Consensus MMA Rankings. Herman is unranked. The PPV card begins Saturday, May 26 at 10 p.m. ET / 7 p.m. PT.

As with a lot of this card, this fight has changed from the original plan. The original fight was Nelson vs. Antonio Silva, but with Alistair Overeem's departure, that was shuffled to Nelson vs. Gabriel Gonzaga, and now Nelson vs. Herman. Both men come into the fight with .500 UFC records, so a win here matters quite a bit. The loser will be on a two fight losing streak, and will quite possibly find himself fighting for his job the next time out.

How do these two stack up?

Nelson: 35 years old | 6'0" | 73" reach
Herman: 27 years old | 6'5" | 77" reach

What have these two done recently?

Nelson: L - Fabricio Werdum (UD) | W - Mirko Filipovic (TKO) | L - Frank Mir (UD)
Herman: L - Stefan Struve (TKO) | W - Jon Olav Einemo (TKO) | W - Yoshihiro Nakao (UD)

How did these two get here?

"Big Country" Roy Nelson is a former IFL champion who came to the UFC through the Heavyweight season of The Ultimate Fighter. He quickly gained a cult following, mainly thanks to his huge belly - a physical attribute Nelson liked to use as part of his persona. But recently, he's been changing that image. He's focused on slimming down somewhat and dropped the "fat guy" idea. Nelson is a skilled grappler who also has dynamite one punch KO power. He's just 1-3 in his last 4, but all of those loses have come against the division's very best.

Dave "Pee Wee" Herman started his career with a solid 15-0 run. He then made the move to Bellator and Sengoku, but various contractual issues frustrated him in those organizations. In 2011, he made the jump to the UFC, defeating Jon Olav Einemo at UFC 131. After that, Herman lost some time in the Octagon due to a failed drug test for marijuana, then came back to loss against Stefan Struve earlier this year. Herman is a Team Quest wrestler, but also prides himself on having exciting fights and going for the finish.

Why should you care?

If you like goofiness, Herman will likely provide. But he's also a pretty entertaining fighter, whether he's on the winning or losing end. Nelson is the same way, and this should produce an entertaining slobberknocker.
