FAQ:

What happens if the Jack does not reach the minimum length or goes in the ditch when the lead delivers it?

• 10 10.3  If the jack is improperly delivered once by each player in any end, it must not be delivered again in that end. Instead it must be centred with the nearest point of the jack to the mat line being 2 m from the front ditch, and the mat must be placed as described in law 6.1.1 by the first player to play.   
• 6.1.1 says – before the start of play in each end, the player to play first must place the centre line of the mat lengthwise along the centre line of the rink, with the mat at least 2 m from the rear and 25m front the front ditch.
