If the ball hits a wall due to a pass or scatter it will bounce one square away from the wall using the template.
When a blocked player is pushed, if there are no empty squares the player can be pushed into a wall.
When a player is pushed into a wall, make an armour roll. If armour is broken the player is Knocked Down in the current square.
If a player is knocked down into a wall, treat the block as being made by a player with mighty blow. If the blocking player already has mighty blow add one to armour and injury rolls.
