Matt Riddle and Francisco Rivera each walked away from UFC 149 on July 21 in Calgary with impressive victories under their belts.
Riddle scored the UFC 149 Submission of the Night bonus for his third-round arm triangle choke finish of Chris Clements, while Rivera knocked out Roland Delorme near the end of round one of their bout.
Both victories have since been rescinded following each man’s positive drug test result following the fights.
The Calgary Combative Sports Commission on Saturday confirmed to MMAWeekly.com that both Riddle and Rivera returned “positive test results for a banned substance while participating in the UFC 149 in Calgary.” The commission did not identify the substances.
Each fighter was suspended for 90 days effective from the date of the offense, July 21.
“It was the Commission’s decision to amendment the results of both bouts these individuals participated in to No Contest because of the positive test results and those amendments have been filed accordingly,” read a commission statement provided to MMAWeekly.com.
The No Contest designation cancelled out what would have been back-to-back victories for Riddle, and nullified what would have been a four-fight winning streak for Rivera.
