Sri Lanka's Kusal Perera faces a four-year ban after the country's sports minister said the wicketkeeper-batsman's 'B' sample has also tested positive for a prohibited substance. The International Cricket Council (ICC) provisionally suspended the 25-year-old after he failed an out-of-competition anti-doping test in October. The ICC has informed that his B sample also has tested positive for a banned drug, Sri Lanka sports minister Dayasiri Jayasekera told reporters today. The cricketer faces a maximum ban of four years according to the ICC's anti-doing code.
