With only a few weeks remaining before the UFC returns to Montreal for UFC 154 a bout has been added to the November 17 lineup, though technically both of the involved fighters are serving as replacements for competitors previously scheduled for the event. According to the UFC, welterweights Matt Riddle and John Maguire will meet in the Octagon on the preliminary portion of the card.

Riddle was recently named as a replacement for the injured Stephen Thompson in a tilt with Besam Yousef (who himself has since withdrawn for unknown reasons, thus opening up the slot for Maguire to slide in).

The 6-3 Riddle is coming off a suspension for marijuana use that cost him a win over Chris Clements this past July when the result was changed to a No Contest. Prior to the bout he’d beaten Henry Martinez, snapping a two-fight skid for the Ultimate Fighter 7 alumnus.

Maguire holds an overall record of 18-4 with ten submissions. However, he came up short last month at UFC on Fuel 5, seeing a seven-fight winning streak laid to waste after being outpointed by John Hathaway.

UFC 154 features Georges St-Pierre defending his welterweight title against interim champion Carlos Condit in the main event with other notable bouts including Patrick Cote-Alessio Sakara and Johny Hendricks-Martin Kampmann.
