As more information becomes available on the incident, it is believed the banned element found in the French international's sample was a fat-burning substance.
That is according to the Associated Press' global football writer Rob Harris, who has been providing information on Sakho's situation via Twitter.
His teammate Kolo Toure served a six-month ban in 2011 for a similar offence and the findings put the defender's Euro 2016 chances in serious jeopardy.
If he is indeed suspended, Sakho will be a big loss for the Reds as they look to reach the Champions League via Europe's secondary competition.
According to Harris, the 26-year-old is yet to request that his B sample be tested by European football's governing body.
