[quote="Wollo-Wollo-Wollo-Wayoo"]The try was OK for me.
Both players were on side
Percival knocked the ball back
It didn't touch the line
Graces right foot was clearly on the ground within the field when he batted the ball back.
Graces left foot was floating in mid air.
What else could disallow it??[/quote
Percival may have knocked the ball back, but I've seen dozens of similar situations where a knock on was given.
I long since gave up knowing what constitutes a knock on, because referees seem to use their own interpretation of the law regarding this.
