Cape Town - Australia batsman Cameron Bancroft was involved in an alleged ball tampering incident on the third day of the third Test at Newlands on Saturday.

EXPOSED: What’s gone down Oz player’s pants?

Before tea, Bancroft was seen pulling out a mysterious object from his pocket.

On-field umpires Nigel Llong and Richard Illingworth approached the Australian opener and when asked, Bancroft decided to pull out a black 'sunglass cloth'.

The umpires decided not to change the ball and Proteas opener Aiden Markram fell shortly after the incident occurred for a well fought 84.

The incident is the latest in a string of controversies to have plagued the series since the first Test in Durban.

Bud you know nothing in professional sport is done without the consent of your captain and coach... Tough times ahead.
