UFC 172 main event fighters Jon Jones and Glover Teixeira are undergoing random drug testing ahead of their light heavyweight championship match later this month.

The two will meet in Baltimore on April 26, and the Maryland Athletic Commission is administrating the testings. The UFC is paying for the tests, according to Jones, who spoke with “UFC Tonight” about the proceedings.

“The Maryland Commission set a lab to drug test me and I’m glad they did,” he said. “It was urine and blood. They had a test for HGH, I think it was HGH, then they had a urine test that detects all the other type of stuff.”

Jones (19-1) said that he and his management team approached the UFC about doing the extra testing. Typically, fighters are tested after bouts by the commission in which the fight is behind held.

“They said they would need the UFC to approve it. The UFC approved it and paid for the whole thing,” Jones stated. “They never told me or Glover when our tests would come.

“I’m happy that it came.”

Teixeira’s team informed MMAjunkie.com that he is also being tested while preparing for the fight.

The use of further testing has become a hot topic in MMA. Former UFC welterweight champion Georges St-Pierre has talked about it, and both the Nevada Athletic Commission and the UFC agreed to ban TRT going forward.
