Simona Halep, the two-time grand slam champion and former world No 1, has been charged with a second anti-doping rule violation while provisionally suspended following a positive doping test last year.
The International Tennis Integrity Agency (ITIA) announced on Friday that Halep’s athlete biological passport (ABP) returned irregularities after an assessment of her profile by an independent expert panel. Anti-doping bodies use the biological passport system to monitor an athlete’s various blood indicators over a long period of time in order to identify irregularities that could indicate rule violations.
