Banned Australian player Cameron Bancroft on Wednesday confirmed David Warner asked him to alter the ball during the tampering scandal in South Africa and said he went along with it "to fit in".

Bancroft was seen using sandpaper to try to rough up the ball in the Cape Town Test in March, receiving a nine-month ban from international and domestic cricket for his part in an incident that rocked the sport.

Warner and then captain Steve Smith were exiled for a year after all three were found to be involved. A Cricket Australia investigation pointed to Warner as the mastermind and Bancroft revealed more details in an interview with former Australia wicketkeeper Adam Gilchrist on Fox Sports.

“Dave suggested to me to carry the action out on the ball given the situation we were in the game and I didn't know any better,” said Bancroft, whose ban runs out this weekend.

“I didn't know any better because I just wanted to fit in and feel valued really. As simple as that.
