Rick Glenn was scheduled to meet Georgi Karakhanyan for the inaugural World Series of Fighting featherweight title, but an injury has forced him to pull out of the fight and Lance Palmer will replace him in the bout. 
World Series of Fighting officials announced the change on Tuesday and the new bout will remain on the main card broadcast on NBC SN.
World Series of Fighting 7 takes place on December 7th from the PNE Agrodome in Vancouver, British Columbia, Canada and will be headlined by a light heavyweight bout as Anthony Johnson meets Mike Kyle.

Karakhanyan (14-3-1) has won eight in a row since exiting Bellator MMA in 2011. During his winning streak, four of those wins have come by submission, including his win over Waylon Lowe in his WSOF debut.
