But the mood changed when referee Probert followed the letter of the law and booked Gray under a mandatory Federation Internationale de Football Association rule that says players must not remove their shirt over their head.
While there has been some anger placed towards Probert for showing the card in the first place, many others understand that he had been put in a hard position in the first place. It was the first match for the team since it lost its owner in the accident.
Tributes were also paid to Vichai and the others killed in the crash at Saturday's match in Wales, where a wreath was laid and a minute's silence was observed.

Erik Lamela put Tottenham ahead in the 27th minute, Lucas Moura doubled their lead three minutes later and Harry Kane notched the third in the 62nd minute.
The home team, though, caused an attack of the jitters for Tottenham after narrowing the deficit to 3-2 with penalties from Ruben Neves and Raul Jimenez, both awarded after fouls by 20-year-old Argentine center back Juan Foyth on his league debut.
