Former England captain Sir Alastair Cook has said that Australian opening batsman David Warner had once unintentionally confessed to him about trying to tamper with the ball during a first-class game. Cook claimed the incident took place once during the celebrations following the Ashes where Warner admitted to using the strapping on his hand to alter the condition of the ball.
"David Warner, a couple of beers into his celebration, mentioned that he used substances attached to the strapping on his hand to accelerate the deterioration of the ball during a first-class match. I looked at Steve Smith who shot a glance that said: 'Ooh, you shouldn't have said that'," Cook revealed in his autobiography.
Warner was banned for 12 months by Cricket Australia (CA) for his involvement in the ball-tampering scandal last year in Cape Town. He was part of the trio of players who were convicted for trying to “cheat” in the Test match against South Africa.
