Jamie VarnerInjuries to Gabriel Gonzaga and Evan Dunham have, yet again, forced changes to UFC 146. Dave Herman and former-WEC lightweight champion Jamie Varner have been tapped to replace the two injured fighters, respectively. The UFC announced the new match-ups earlier today.

Dave Herman was last in action at UFC on Fuel TV 1, a bout he lost to Stefan Struve. Herman will look to regain the momentum he had before the loss to Struve. That will prove a tough task as he will be facing fan-favorite Roy Nelson.

After an injury left Evan Dunham unable to fight at UFC 146, former WEC champion Jamie Varner will step in to face Edson Barboza. Varner has gone 3-1 since leaving Zuffa when the WEC was merged with the UFC.

UFC 146 will be headlined by a heavyweight title fight between champion Junior Dos Santos and Frank Mir. The main card will feature an all heavyweight lineup for the first time in the modern history of the UFC.
