Mitchell escapes further penalty
Wallabies' winger Drew Mitchell has escaped further sanction after being sent off in the Tri-Nations thrashing by the All Blacks.
Mitchell had to front a judiciary hearing on Sunday after referee Craig Joubert sent him off in the 43rd minute for his second yellow card offence.
However SANZAR's judicial officer Peter Ingwersen decided missing almost half the match was penalty enough.
