UEFA on Friday dropped proceedings against Liverpool and France international defender Mamadou Sakho over a doping infringement, European football's governing body said.

"Following a hearing with the lawyers of the player and experts of the WADA-accredited laboratories on this case, the CEDB has decided to dismiss the case," UEFA said in a statement, referring to its independent Control, Ethics and Disciplinary Body.

Sakho, 26, who was left out of the French squad for the European Championships, tested positive after a Europa League tie against Manchester United on March 17 after taking a product to reduce body fat. He served an initial 30-day suspension that was not extended.

The centre-back is said not to have known the composition of the weight-loss supplement and informed UEFA that he had acted in good faith.

The player was technically available for international duty at Euro 2016, but despite playing a key role for France these last two seasons Didier Deschamps left him out of the finals squad.
