Nick Kyrgios demands Yannick Sinner's suspension after failed doping tests
Australian tennis player Nick Kyrgios has reacted to the news of positive doping tests involving world number one, Italian Jannik Sinner.
Earlier, ATP issued a statement regarding Sinner's positive doping tests.
On Tuesday, it was revealed that the world number one avoided disqualification as it was determined that the samples were contaminated by a spray the physiotherapist used to treat a cut on his own finger.
