LAS VEGAS — Nevada athletic regulators have extended a temporary suspension of UFC heavyweight Brock Lesnar pending a hearing on his failure of drug doping tests at UFC 200 last month.

State Athletic Commission officials say the move approved Tuesday came after the U.S. Anti-Doping Agency found violations of UFC drug policy in June and at Lesnar’s July 9 fight against Mark Hunt.

The UFC said the 39-year-old Lesnar tested positive both times for an estrogen blocker, clomiphene, and its metabolite.

A representative for Lesnar didn’t immediately respond Tuesday to a message seeking comment.

The earliest Lesnar could be scheduled for a Nevada commission hearing is September.

He could face a two-year suspension, along with fines.

Lesnar beat Hunt by decision, winning his first mixed martial arts fight in 4½ years.
