Earlier tonight news broke that former UFC heavyweight champion Brock Lesnar had been flagged for a potential anti-doping violation.

The out-of-competition drug test in question was performed by USADA on June 28, 11 days prior to Brock Lesnar’s UFC 200 decision victory over Mark Hunt.

Of course it did not take long for fellow UFC fighters to chime in on the situation.

Here is what the pros had to say about Lesnar’s potential anti-doping violation:
