Maguire meets Riddle at UFC 154
Britain's John Maguire will step in for Besam Yousef and face Matt Riddle at UFC 154 in Canada on November 17.
Yousef has been forced out of the welterweight contest after picking up an injury during his preparation for the bout.
Maguire has won two of his three UFC fights since making his debut in November 2011, the defeat coming against John Hathaway in Nottingham last month.
America's Riddle is 6-3 in the UFC with one no contest, which was declared after it was announced he failed a drug test - testing positive for marijuana - following a defeat of Chris Clements at UFC 149 in July.
