Quote: orford_addict "Yes.....the term is used to define any leg tackle from the side when a player is already held (momentum stopped) in the standing position......
The technique is banned in the NRL because of the potential career threatening injury risk from knee or ankle (aka Ratchford's injury) ligament damage and the RFL are looking at banning here also in 2014
Hansen isn't a dirty player and am sure it wasn't malicious'"
I think you need to look the definition of leg, side and momentum.
Hansen hit the hip/lower back from behind and Ratchford was still attempting to push forward (tackle was not complete). In no way was it a cannonball tackle, hence why he was cleared.
