Liverpool defender Mamadou Sakho has been handed an initial 30-day ban by UEFA, who have now opened a disciplinary investigation against the France international.
Sakho recently failed a drugs test for a suspected fat-burning drug, leading to Liverpool making him unavailable for selection while the disciplinary process is carried out.
A statement from UEFA read: “Disciplinary proceedings have been instigated against Liverpool FC player Mamadou Sakho, following the UEFA Europa League round of 16 second-leg match between Manchester United FC and Liverpool FC (1-1), played on March 17.
“The proceedings relate to a violation of the UEFA anti-doping regulations, after the player failed a doping test at the above-mentioned match.
“The player did not request the analysis of the B sample. UEFA has now suspended the player provisionally for 30 days until a final decision is taken by the UEFA control, ethics and disciplinary body.
“The date of the disciplinary hearing will be announced at a later stage.”
It is believed the length of Sakho’s potential ban could be reduced due to the fact he did not contest the charge, nor request his ‘B’ sample be tested.
Sakho has not travelled with the Liverpool squad for their clash with Villarreal on Thursday night and is not expected to feature for the Reds again this season.
