The Ultimate Fighting Championship’s upcoming, August 17th return to Boston is reportedly in trouble, due to a Massachusetts law that requires foreign fighters to have a Social Security number so that they can be licensed. As per usual with most UFC cards, several foreign fighters are scheduled to compete at the UFC on FS1 1 event, including headliner Mauricio “Shogun” Rua.

In a report from the Boston Herald Tuesday, spokesman for the state Department of Public Safety Terrell Harris was quoted saying:

“This law has been in existence since we legalized mixed martial arts in the commonwealth of Mass­achusetts”

“It’s been brought to the attention of the UFC more than a few times since we legalized the fighting here. But they’ve chosen basically to ignore the law and hope that they could skirt it somehow”

The report furthers that the Social Security Administration gives fighters a 10 day grace period, in terms of applying for a temporary Social Security number, however, it’s up to the promotion to kick start process. Harris says that the UFC has asked for exemption instead.

UFC 118 was held in Boston in August, 2010, which featured several foreign fighters including Demian Maia, Mario Miranda and Andre Winner. The UFC has not, as of yet, made any statement regarding the Herald report.

UFC on FS1 1 will be hosted by Boston’s TD Garden Arena and will feature Chael Sonnen taking on Rua in the main event. Considering the amount of cash a UFC event generates in any city, it’s hard to imagine that officials won’t come up with some sort of solution.
