All fighters who underwent drug testing at this past month’s UFC 161 event successfully passed their tests. MMAjunkie.com (www.mmajunkie.com) confirmed the results with Marc Ratner, the UFC’s senior vice president of government and regulatory affairs. The Manitoba Combative Sports Commission oversaw the testing. UFC 161 took place June 15 at Winnipeg’s MTS Centre, and Rashad Evans took a split decision from fellow light heavyweight Dan Henderson in the pay-per-view main event.
