Former heavyweight champion Brock Lesnar has quit UFC, according to reports in the USA.
Lesnar has not made an official announcement but his name has been removed from the USADA drug-testing pool and MMAfighting.com reports the 39-year-old has informed UFC of his retirement.
Last month, Lesnar was banned for a year after failing a drugs test.
He tested positive for clomiphene and its metabolite, 4-hydroxyclomiphene, during an out-of-competition urine test.
Now a huge star in WWE, Lesnar returned after five years away from MMA and beat Mark Hunt in what may prove to have been his last appearance, at UFC 200.
But his victory was overturned following the failed drugs test.
