Things are not getting any better for Brock Lesnar.

The former UFC heavyweight champion and current WWE star also failed an in-competition drug test at UFC 200, the UFC announced Tuesday afternoon. It was previously announced Friday that Lesnar had failed an out-of-competition drug test from a June 28 sample taken by USADA, the UFC's anti-doping partner.

Lesnar failed both tests for the same banned substance, the UFC release stated. USADA has yet to reveal the name of the drug and won't unless Lesnar makes it public first himself.

This positive drug test will likely be lumped into the previous one as a single potential anti-doping violation. According to the UFC's anti-doping policy, two positive tests could be considered aggravating circumstances, which could lead to further sanctioning. In-competition is considered the 12-hour window before and after a fight.

Lesnar, 39, is facing at least a two-year ban from the UFC, but will get a full adjudication process first from USADA. The Nevada Athletic Commission (NAC) also has jurisdiction in both cases, so Lesnar is likely to get sanctioned by both bodies.

Last week, USADA confirmed that Lesnar had passed multiple drug tests before failing the one from a June 28 sample. Lesnar was tested eight times in total in the month leading up to UFC 200. He passed the first five tests and now failed at least two of the last three.

Lesnar told the Associated Press in a statement last week: "We will get to the bottom of this."

At UFC 200, Lesnar defeated Mark Hunt by unanimous decision. That result will come into question before the NAC at a disciplinary hearing later this year. The fight was Lesnar's first in the UFC since 2011. The UFC waived a rule in its anti-doping policy that states a retired fighter must notify USADA four months out of a comeback fight to be placed in the testing pool.
