The Wilson "knock" that ended in a try against Italy is an interesting one

See TASanalytics video. The law makes provision for the ball going forward from the ripped player being play on. But was this dislodged by the rip or did Wilson just lose control of it. It's not as clear cut as it looks. Very tough decision to make.

knock on for moi

Rip for me.

Even though Zuliani's rip attempt wasn't clean his actions dislodge the ball. Seconds 1.47 to 1.50.
