The UFC on Fox 19 card has taken another hit, as the lightweight bout between Islam Makhachev and Drew Dober has been canceled after Makhachev tested positive for a banned substance.
The UFC released a statement on Friday evening announcing that Makhachev was flagged for a potential anti-doping violation involving Meldonium stemming from an out-of-competition sample collection. Makhachev received a provisional suspension as a result of the test.
According to BloodyElbow.com Meldonium is a medication used to increase bloodflow in patients with heart conditions and has been commonly used by athletes in Eastern Europe and Russia as a supplement.
