Keith Hackett's verdict

1) The guidance on this is clear: only caution a player for taking off his shirt, or lifting it over his face, if he's celebrating a goal. In this case, the player clearly isn't celebrating, or deliberately inciting the crowd, so just have a quiet word. You'd only show him a yellow card if his behaviour delayed the restart. Thanks to Jason Kilby.

2) The law defines how actions such as throw-ins should be carried out, but clearly you can make concessions for players with disabilities. Your judgment must be based on fairness: if the player delivers the throw from behind and over his head, there's no need to intervene. Two-handed throws where one hand is behind the ball with the other hand used as a guide are illegal. Trevor Selman wins the shirt.

3) The original keeper can take no further part and must leave the field. Allow the sub keeper to return and replace him, and caution both for failing to inform you of the change. As for the restart: if the offending team have not had a goal scored against them since half-time, restart the second half. If they have conceded, restart with an indirect free kick taken from where the ball was when you stopped play. Thanks to Harry Glenister.
