Christian Pulisic has been ruled out of AC Milan's Serie A clash against Atalanta on Sunday due to a glute muscle injury, according to multiple reports. The American winger, who was slated to start, pulled up during Saturday's training session, casting a shadow over his preparations for the upcoming World Cup.

The 27-year-old will undergo further tests to determine the severity of the injury, and the U.S. men's national team will be monitoring the situation closely with just a month to go before the tournament kicks off. Pulisic has struggled for form recently, enduring a career-worst 17-match goalless streak for AC Milan since his blistering start to the season, which saw him net 10 times in the first half. He also hasn't found the back of the net for the USMNT since 2024, but remains a key figure in the squad's plans for this summer.

In a recent interview with Time Magazine, Pulisic dismissed concerns over his dip in form ahead of the World Cup. When asked if he had a message for those worried about his scoring drought, he replied bluntly: "Such bad questions. I'm not concerned about it, man."

The USMNT opens their World Cup campaign against Paraguay in Los Angeles on June 12, followed by group-stage matches against Australia and Turkey. With Pulisic's fitness now a question mark, fans and teammates alike will be hoping for a swift recovery as the team gears up for the biggest stage in soccer.
