Mike Tyson and Roy Jones Jr. are scheduled for an exhibition bout in California on September 12, but the two fighters still have a major hurdle to clear.

According to Ryan O'Hara of The Ring, the Voluntary Anti-Doping Association wants to administer random drug testing for Tyson and Jones.

“Drug testing is the major concern for this event,” one source said about the potential Mike Tyson fight. “That needs to be the focus, not the size of the gloves, or the headgear.”

The Ring was unable to reach VADA president Dr. Margaret Goodman for comment.

In 2019, Godoman said that VADA typically conducts 40-50 drug tests a month. However, during a recent interview with KSNV, Goodman revealed that that number has been decreased due to the coronavirus pandemic. She did not specify how much.

The Ring also stated last Wednesday that headgear was an issue for the match. With Mike Tyson being 54 years old and Jones coming in at 51, many have wondered if headgear should be necessary for the two aging fighters. As of right now, the California State Athletic Commission is leaning toward no headgear.

Contracts for the fight were signed in June, but because of the COVID-19 pandemic, the two sides delayed the announcement for the bout in order to give fans the opportunity to potentially attend.

Mike Tyson last fought back in June 2005, when he lost to Kevin McBride via RTD. He owns a lifetime record of 50-6, with 44 of his wins coming by knockout.

Meanwhile, Jones' most recent bout came in February 2018, when he topped Scott Sigmon via unanimous decision.
