Ex-Manchester City midfielder Samir Nasri has been banned from football for six months because of a drip treatment he took at a Los Angeles clinic in 2016, his lawyer said.
Nasri, 30, took the treatment while on holiday, but it contravened World Anti-Doping Agency (Wada) rules leading to a Spanish Anti-Doping investigation.
Nasri’s lawyer told BBC Sport the suspension was being imposed by Uefa.
Reports in Spain have suggested the ban will be made public on Monday.
Nasri, who is without a club having left Turkish side Antalyaspor in January, received treatment from a private medical company, Drip Doctors, in his hotel room.
Wada rules state there is a 50 millilitre infusion limit per six-hour period for active athletes but it was alleged he received 500 millilitres of hydration in the form of sterile water containing micronutrient components.
In February 2017, a request by Sevilla for a retroactive therapeutic use exemption (TUE) for Nasri was refused by Uefa, whose decision was later upheld by the Court of Arbitration for Sport.
