Celtic star 'isolated' after falling ill as Parkhead teammate involved in 'crazy situation'

Nygren has been isolated from the rest of the national squad along with Brighton's Yasin Ayari and former Celtic defender Gustaf Lagerbielke ahead of Friday's Nations League clash against Bosnia and Herzegovina.

Swedish outlet Fotbollskanalen report that all three missed training on Wednesday and have been kept at the team hotel.

"Cold symptoms," explained Sweden press officer Petra Thorén. "They are being kept isolated so that we keep this down to as few people as possible."

Asked whether the players will be ruled out of the trip to Zenica, she added: “Far too early to say. We’ll see how things develop.”

She was then asked whether the players would need to be fully recovered before getting on the plane.

“I assume they have to be. But it’s too early to say. The information that they’d become ill came today.”

Nygren scored the opener as Sweden beat Poland 3-1 on Monday to move top of their Nations League group with six points from six. Bosnia and Herzegovina sit second on four points.

Elsewhere, Celtic defender Auston Trusty was involved in a major scuffle near the end of USA's 4-2 win over Chile.

Players from both sides grappled with each other after Chile attacker Leando Hernandez attempted to kick the ball out of USA goalkeeper Brian Schwake's hands after running the down the clock.

Trusty was one of the first players on the scene as a chaotic shoving match ensued that saw both benches spill onto the pitch but only Chris Richards and Hernández were issued yellow cards for their roles in the confrontation.

USA head coach Mauricio Pochettino described the fracas as a "crazy situation", adding: "You try to divide the players and calm down. Sometimes, when you are winning you have to understand the opponent may go to the line and walk over the line in frustration.

“I don’t like it,” he added. “When I was young, yes, I liked a lot to fight. Now I’m more relaxed. I don’t have the same reflexes, and I am not as fast if I need to move and run.”
