Where do other players stand during a wheelchair delivery, and when is a stone in play?

Non-delivering team (R14(c)): during delivery, the non-delivering team's players must take stationary positions behind the back line at the delivering end. However, any two players may take stationary positions behind the back line at the playing end, as long as they do not interfere with the choice of place of the delivering team's skip or vice-skip.

Delivering team's house position (R4(b)): the player in charge of the house is positioned inside the hog line with at least one foot or wheel on the ice surface of the playing end of the team's sheet while the team is delivering.

Stone in play (R5(g)): in wheelchair curling a stone is in play when it reaches the hog line at the delivery end. A stone that has not reached that line may be returned and redelivered.

Release (R14(b)): the stone must be clearly released from the hand or stick before it reaches the hog line at the delivery end.

Penalty (R14(e)): if a delivery violation occurs, the delivered stone is removed from play and any displaced stones are replaced by the non-offending team.
