UFC strawweight Jessica Penne has been flagged for a potential doping violation by the United States Anti-Doping Agency.

The test in question was an out of competition sample taken on March 20th which was originally ruled to have no traces of banned substances, however Penne’s biological passport led to a retest  which turned up a prohibited substance.

Penne fought and lost to Danielle Taylor at UFC Fight Night Nashville on April 22, after the original test was clean.

Penne is provisionally suspended while USADA works with the Tennessee Athletic Commission which has jurisdiction in the case.
