VANCOUVER — Though it was the biggest day in Canadian men’s soccer history, heavy hearts clouded celebrations in Vancouver following Canada’s 6-0 thrashing of Qatar for their first-ever win at a World Cup.Midfielder Ismaël Koné suffered a serious left leg injury when he was fouled early in the second half by Qatar midfielder Assim Madibo. Players nearby reacted with immediate horror, as did the Canadian bench, who were only a few feet away from the incident.“You could hear the bone snap,” Canada head coach Jesse Marsch said after the game, saying Koné is at the hospital preparing for surgery. “Your heart goes out to him. Everybody’s shaken for him.”Immediately after the news conference, Marsch said he was leaving the stadium to be with Koné and his family at the hospital. The team is having a family barbecue together on Friday. Marsch said Koné will be on everybody’s minds.What was an unfathomably loud stadium for the first 51 minutes drew silent as fans realized what happened to Koné. Players were visibly shaken up. Richie Laryea turned his shock to anger, going up to confront Madibo. Some brief arguments sparked on the pitch and between the benches as other players gathered to be by Koné’s side on the stretcher.“It hurts so much (because of) his love of the game,” defender Alistair Johnston said. “To see someone like that go down on such a needless challenge, it’s frustrating.”(Reuters / Agustin Marcarian)As the medical team got Koné’s leg stabilized and the stretcher ready to be moved, Marsch and Koné shared a big hug. The 24-year-old, aware of the fear and hurt in the stadium, gave a big thumbs up to the crowd. As he was being wheeled away, between taking breaths from an oxygen tank on the stretcher, he waved to the crowd.
