Cub SwansonIt’s rare to see a late replacement result in a superior scrap but many would argue that is the case regarding a recently announced change to the lineup for UFC on Fuel 7. According to UFC officials, featherweight Dennis Siver has been forced to withdraw from a scheduled clash with Cub Swanson for undisclosed reasons. Fortunately, the UFC also confirmed Dustin Poirier had agreed to action against Swanson and will be taking Siver’s spot in the February 16 fight.

The 23-year old Poirier positioned himself to earn a title-shot after going 5-0 in the Octagon but came up short in a bout with fellow contender Chan Sung Jung. He bounced back victoriously last December, submitting Jonathan Brookins in the opening round of action at the Ultimate Fighter 16 Finale to improve his overall record to 13-2 including eleven finishes.

Swanson (18-5) is one of the hottest 145ers out there right now, stringing together consecutive knockouts of George Roop, Ross Pearson, and most recently Charles Oliveira. Fourteen of his wins have involved some form of stoppage.

UFC on Fuel 7 is scheduled to take place in London, England where a title-fight between interim bantamweight champ Renan Barao and surging youngster Michael McDonald will serve as the evening’s main event.
