However, ESPN.com has obtained two separate written reports sent by VADA's president, Dr. Margaret Goodman, to both camps as well as the WBC, whose title Wilder holds, notifying them that Povetkin was negative for any banned substances in VADA-conducted tests on April 7, April 8 and April 11. So Povetkin, who has yet to ask for his B sample to be tested, apparently used meldonium between April 11 and his positive test on April 27.
The letter Goodman sent disclosing the negative results on April 7 and April 8 was sent on April 21. The letter confirming the negative results on April 11 was sent on April 30.
"The information you have obtained is accurate," promoter Lou DiBella, who represents Wilder, told ESPN.com on Saturday. "It also contradicts the public statements made by Mr. Ryabinsky attempting to excuse Povetkin's positive result. If there was a trace amount from 2015 in his system, it would have shown up in the other three tests in April that preceded the positive result.
