Here are Keith Hackett’s answers to yesterday’s “You Are the Ref puzzler”. If you missed it, you can view it here.
1) Another scenario that shows you need to be ready for anything. In theory this should not happen: competition regulations will mean these details are set out well in advance – and for Uefa games a meeting takes place at 10.30am on the day to check team colours, logo sizes, ball boy colours, warm up bib colours and other details. However, there is nothing in the rules to stop teams changing to an alternative strip at half-time, unless it would mean a colour clash – remember Manchester United and those famous “invisible” grey shirts at Southampton in 1996? So allow the swap to take place.
2) It’s all in the timing. If you were whistling as the defender caught the ball, that’s fine: arrange treatment and restart with a dropped ball. But if not, you need to take action. Players should not be taking the law into their own hands, whatever the motive. So award a penalty kick, signal for the medics to come on – and, if the ball was going in, show the defender a red card. Thanks to Bongai Jinguri.
3) Play the game. The colour of line markings is not covered in the Laws – they just need to be distinct. Clubs often use green sand to cover over any confusing lines. Thanks to James Francis.
