Two fighters suspended following failed UFC 149 drug tests

Following July's UFC 149 event, welterweight Matt Riddle was flagged for marijuana while featherweight Francisco Rivera tested positive for an undisclosed over-the-counter stimulant.
Both fighters were suspended for 90 days retroactive to the July 21 event, which makes them eligible to fight on Friday. The results of their respective bouts were not changed.
According to sources close to the competitors, both fighters declined to appeal their punishments and apologized for their actions.
Shirley Stunzi of the Calgary Combative Sports Commission, which oversaw the pay-per-view event, declined comment for this story.
