Australia captain Pat Cummins has strongly criticised former teammate Usman Khawaja over his 'utter nonsense' allegations regarding the 2018 South Africa ball-tampering scandal, accusing him of being 'casual with lives and reputations' in his autobiography.

Addressing reporters at Sydney's Cricket Central, Cummins, as quoted by Fox Sports, flatly rejected claims that the bowling quartet of himself, Mitchell Starc, Josh Hazlewood, and Nathan Lyon knew sandpaper was taken onto the pitch.
