Matt Brown out of upcoming bout with Carlos Condit

UFC welterweight Matt BrownNext Weekend’s UFC on Fox 9 card has taken a major blow. Matt Brown has been forced out of his scheduled bout with Carlos Condit due to injury. The veteran welterweight announced the news over the weekend through his Twitter account. The UFC has yet to confirm the change to the card, which takes place Dec. 14 at the Sleep Train Arena in Sacramento.

According to his Twitter post, the injured occurred when Brown “herniated two discs in my lower back this week.”

Brown has unlikely fought his way into title contention. He won six-straight fights since falling by guillotine to Seth Baczynski in 2011. The action fighter made his UFC debut in 2008 after competing on the seventh season of “The Ultimate Fighter.” This year, he has picked up victories over Jordan Mein and Mike Pyle.

Condit recently got back on track with a fourth-round knockout of Martin Kampmann. He had previously dropped back-to-back fights for the first time in his career. From 2009-2012, Condit won five-straight fights and captured the interim welterweight title with a victory over Nick Diaz at UFC 143. At UFC 154, he challenged champion Georges St. Pierre for the belt, but he dropped a five-round decision. In 2007, Condit defeated John Alessio for the WEC welterweight title. He defended it three times before the WEC was folded into the UFC.

In the main event of UFC on Fox 9, flyweight champion Demetrious Johnson will defend his title against Joseph Benavidez. Johnson previously defeated Benavidez via split decision to claim the inaugural flyweight title.
