Not last feet, not a dummy, not 50-50.

Sarel Pretorius of Griquas puts the ball into a scrum and Griquas are heeling it, rickety though it is.

The ball is in the scrum when Tewis de Bruyn (9) starts moving infield. The referee penalises De Bruyn.

Law 20.12 (e) The scrumhalf whose team does not win possession of the ball must not move away from the scrum and then remain in front of the offside line. For that scrumhalf that the offside line] runs through the hindmost foot of that player’s team in the scrum.
Sanction: Penalty Kick

De Bruyn moves infield. He is a long way in front of the last man's feet. He is offside.
