Tom Lawlor is the latest UFC name to be sanctioned by USADA.

The popular UFC light heavyweight was suspended two years by the UFC’s anti-doping partner after a positive test for the banned substance ostarine, USADA announced Friday.

Lawlor was flagged for a potential anti-doping violation in November following the failed drug test from an Oct. 10 sample. His suspension is retroactive to that date, so he will be able to return in October 2018.

Ostarine is a selective androgen receptor module (SARM) with benefits similar to anabolic steroids, retaining and, at times, producing lean muscle. It’s in the Anabolic Agents portion of the World Anti-Doping Agency (WADA) Code.

In the release, USADA states that ostarine is “not currently available as a prescription medication in any country, and its unauthorized use may carry serious side effects.” Ostarine has been found as a declared and undeclared ingredient in dietary supplement found in the U.S., prompting the Food and Drug Administration (FDA) to issue a warning letter to certain supplement manufacturers saying ostarine is unapproved and in violation of the Federal Food, Drug and Cosmetic Act (FDCA), USADA said.

UFC welterweight Tim Means tested positive for ostarine last year, but claimed it came from a tainted supplement and a USADA investigation found that it likely did. Means got a reduced suspension of six months, rather than the full two years.

Lawlor, 33, is the seventh UFC fighter to be given a full, two-year ban by USADA since the UFC’s anti-doping program began in July 2015. Lawlor joins the likes of Chad Mendes, Mirko Cro Cop and Gleison Tibau on that list.

In his last bout, Lawlor (10-6, 1 NC) fell by unanimous decision to Corey Anderson at UFC 196 in March 2016. He won two straight before that. Lawlor, a fan favorite for his funny walkouts and weigh-in antics, has been in the UFC since 2008.
