Bellator MMA middleweight  Doug Marshall (18-7 MMA, 4-1 BMMA) failed a post-fight drug test following a knockout loss to champ  Alexander Shlemenko (49-7 MMA, 10-1 BMMA) at this past month’s Bellator 109 , according to a brief from TheMMAReport.com . Marshall tested positive for an undisclosed banned substance and is suspended for an unknown period of time, the head of Pennsylvania’s athletic commission told the website. A source familiar with the administrative action today told MMAjunkie that Marshall is suspended until Feb. 7 and must pay a fine, as well as retake a test, though the type of test is unknown. As with most major state athletic commissions, the Pennsylvania State Athletic Commission tests for performance enhancers and drugs of abuse. PSAC Executive Director Gregory Sirb and Marshall could not be reached for comment.
