The start of the second half was delayed in Ibrox after the rocket was fired at the end of the Celtic goalkeeper, Joe Hart, from a tribune that hosted Rangers fans. Broken glass appeared in pieces on the surface of the game, with Hart demanding that the debris be cleaned from the park before the game started. Several members of Ibrox’s ground staff ran to the pitch in an attempt to secure the 18-yard box again before the second half began.

Sky Sports commentator Ali McCoust described it as an act of “gross stupidity”, while colleague Andy Walker also hit the rocket that came from the end of the fire. Walker believes the moment of madness is damaging the reputation of the world-famous derby. The former Celtic striker said: “We are trying to sell this game all over the world. It is a shame that someone would throw anything on the pitch, let alone a broken bottle. Dismayed Rangers hero McCoist added: “You think nothing will surprise you anymore, but he loved me. Great nonsense.” After the game, Gers boss Giovanni van Bronckhorst knocked down the culprit for delaying the restart and making the pitch unsafe for players. A Scottish police spokesman said: “We know a glass bottle is being thrown at the Ibrox Stadium in Glasgow during the Rangers – Celtic match on Sunday, April 3, 2022. “Investigations are currently underway to determine the full circumstances.” Celtic increased their lead at the top of the Premier League to six points with only six games left after today’s victory in the derby. The hosts took the lead after just three minutes with Aaron Ramsey finishing coolly to give the Rangers a perfect start. But just four minutes later, Tom Rodzic equalized for the Hoops, scoring from close range after Alan McGregor blocked a shot by Reo Haate. And Carter-Vickers, the leader of Sky Sports’s match, would prove to be the winner of the match when he delivered a decisive blow after the Light Blues failed to face a foul by Celtic.
