It was an emotional day at the Cardiff City Stadium as Leicester City played their first game since their owner tragically passed away last Saturday.Vichai Srivaddhanaprabha was involved in a helicopter crash that claimed the lives of the five people on board.Leicester would have wanted to put in a performance to honour Srivaddhanaprabha and they did just that.The Foxes would prevail 1-0 thanks to a goal from Demarai Gray.But the day was not without controversy, however.Shortly after scoring, Gray took off his shirt to reveal an undershirt with the message 'For Khun Vichai'.It was a lovely tribute but, according to the rule book, Lee Probert felt as if he had to book Gray for his actions.His decision to give Gray a yellow card brought about a great deal of criticism, with many condemning Probert.Piers Morgan is just one of the few big names that expressed their anger at Probert's actions, with Morgan labelling him a 'disgrace'.Claude Puel, Leicester's manager, had a very mature reaction to Probert's decision."We played like professionals and it was important for the referee to be professional too," Puel said while reflecting on the incident, per the BBC.A very classy reaction from Puel.And Gary Lineker was another to defend Probert.The former Leicester player made reference to Puel's words and commented that there is 'more important things to worry about'.Discussing the incident on Match of the Day, he said: "There has been a lot of talk on social media about it - people thought perhaps he should have overlooked it and perhaps he should have, but in the bigger scheme of things there are more important things to worry about."

Lineker then took to Twitter afterwards, saying it's a 'silly law' but there's no point getting worked up about something so significant.

Well said, Gary. Probert was just doing his job, and he could potentially have found himself in hot water had he not booked Gray.

This should be a nothing incident given what Leicester City and the footballing world have gone through in the past week.

Fans calling him a 'disgrace' are taking proceedings way too far and Puel and Lineker were right to recognise that.
