Ugly Warner under scanner after angry fight with de Kock (Durban)

David Warner is being investigated after video footage emerged of the Australia vice-captain having an ugly exchange with South Africa's Quinton de Kock during the tea break on day four.

Former Australian team mates Adam Gilchrist and Brad Hogg come down hard on Warner after video footage of the incident from the security camera was leaked.

Former Proteas captain Graeme Smith was scathing of Warner stating that "The Aussies were pretty fired up at that time pushing for a victory".

Warner has a string of offences in his career where he has lost his cool and hit out at opposing players.
