Former French Open finalist Sara Errani must serve a twomonth doping ban after testing positive for the banned substance letrozole in a test taken in February, the International Tennis Federation said Monday. Errani blamed contamination from her mother’s breast cancer medication. “I never took, in my life and during my career, any prohibited substance,” Errani said in a statement. “I am extremely disappointed but at the same time at peace with my conscience and aware I haven’t done anything wrong.” An adjudication panel ruled that Errani’s fault was “at the lower end of the scale,” but she should still be banned for two months. The Italian has been retroactively disqualified from tournaments from Feb. 16 through June 7.
