Christian Pulisic, the United States forward, was sidelined for AC Milan's Serie A match against Atalanta on May 11 due to a lower back injury. This injury adds to the challenges for Pulisic, who is already facing a significant goalscoring drought, having not found the net in 17 league matches since December 28. Reports indicate that he felt discomfort during a training session on Friday, leading to the decision that he could not even be on the bench for the match. Milan suffered a 3-2 defeat to Atalanta, leaving them at risk of missing out on next season's UEFA Champions League. Currently, Milan holds the fourth position, tied on points with fifth-place AS Roma and only two points clear of Como. Pulisic is expected to undergo medical tests on Monday, with uncertainty surrounding his availability for the next match against Genoa. However, he may return for the season finale against Cagliari. Despite his struggles at the club level, Pulisic is not expected to miss the upcoming World Cup, with the U.S. set to play friendlies against Senegal and Germany before starting their campaign against Paraguay on June 12.
