Canadian welterweight Ryan Dickson, a 24-year-old cancer survivor, has replaces and injured Ryan Chiappe and now meets Marcus Vinicius at next month’s “World Series of Fighting 7: Karakhanyan vs. Palmer” event.

WSOF officials recently announced the change.

Dickson (6-1) and Vinicius (9-6) now meet on the preliminary card of the Dec. 7 event, which takes place at PNE Agrodome in Vancouver, British Columbia, Canada and precedes the night’s four-fight NBC Sports Network-televised main card.
