Auckland centre Sam Tuitupou has received a six-week ban after being cited for stamping during Tuesday's game against the Lions at Eden Park.

Tuitupou, capped seven times by the All Blacks, was cited by independent match commissioner Dennis Wheelahan.

And the 23-year-old appeared at a disciplinary hearing in Auckland on Wednesday, when he pleaded guilty to stamping on Lions centre Gordon D'Arcy.

The punishment was handed down by judicial officer Terry Willis, and means that Tuitupou is now sidelined from rugby until August 19.

Lions prop Graham Rowntree was cited for punching in the same game, and his disciplinary hearing is now under way.
