Juventus midfielder Paul Pogba has been provisionally suspended for an anti-doping offence, according to Italy’s national anti-doping tribunal.

The test, performed after Juve’s victory at Udinese on August 20, detected elevated levels of testosterone, a hormone that increases athletes’ endurance.

Nado Italia, the anti-doping agency, said that Pogba was suspended provisionally with immediate effect. Pending a trial and testing of a backup “B” sample, he risks a suspension of up to four years.

It’s another negative note for a player who has been bothered by injuries ever since rejoining Juventus from Manchester United a little more than a year ago. He was ruled out of France’s run to the World Cup final last year due to a knee injury.
