It is permissible for attacking player/s to lend weight to the ball-carrier with an objective of not losing ground. The referee will call 'Held' when this occurs.
It is not permissable for the attacking player/s to impede any defender from making a tackle. The referee will penalise if this occurs.
When a ball carrier has been lifted to a position where he has no control over his momentum, the referee will deem the ball carrier has succumbed to the tackle.
Note: The referee will take into account any momentum the tackle has generated after 'Held' has been called.
