Missed the incident last night, just seen it for the first time.
Nothing wrong with it in the slightest. Tackle was still in progress - no whistle, no 'held', so play on and feel free to hit the attacker.
Tough for KFC he couldn't take a hit from little Sam, and spat his dummy. Are you telling me none of the Saints players would have hit a Wigan player in the same situation?? Didn't Ginger Graham smash into Bailey as third man while Bailey was motionless and prone to attack?
Saying that, Sam is a boney bugger, they're always the ones that hurt!
