Keith Hackett's verdict

1) It's a horrible incident, and you should apologise for your part in it – but you'll also have to show the player a red card for violent conduct. Your action was accidental, his was not: players simply cannot manhandle officials. The Referees' Association considers it an assault. Restart play with the free-kick for which you had originally stopped play.

Gary Brown wins the shirt for this question.

2) The words are not offensive, the pitch is undamaged, and the ink isn't dangerous to players – so the game can go ahead. But you should still make every effort to see if the groundsman can paint over it with green dye or use coloured sand: you have a responsibility to the image of the game. Personally, I'd be confident that the ground staff could come up with some sort of solution: for me, they are the unsung heroes of the game. Thanks to Karl Stringer.

3) The team have not gained an unfair advantage with the shirt mix-up, so there's no need to be draconian about this. Award the goal, and get the player to replace his shirt with one of the spares that are always available (in case of blood contamination or damage). Thanks to Lewis Corner.
