John “Guns” Gunderson announced today that he was forced to withdraw from his upcoming fight with Gesias “JZ” Cavalcante due to a neck injury suffered in training. He made the announcement on “In the Cage with Bards” on NSSRadioTV.com.

The issue stems from bulging discs in his neck, aggravated by a guillotine in training. Gunderson hopes to resume training in just over a month and will return to compete under the World Series of Fighting banner.
