Sept 11 (Reuters) - Juventus's France midfielder Paul Pogba has been provisionally suspended after testing positive for a banned substance, Italy's national anti-doping (NADO Italia) tribunal said on Monday. The test, performed after Juve's 3-0 Serie A season-opening victory at Udinese on Aug. 20, detected testosterone, a hormone that increases athletes' endurance. The tribunal said Pogba had violated anti-doping rules when they found the prohibited substance "non-endogenous testosterone metabolites", adding that the results were "consistent with the exogenous origin of the target compounds". The 30-year-old Pogba was an unused substitute in the win at Udinese. If found guilty of doping, Pogba could be suspended for between two and four years.
