Chelsea ace Christian Pulisic is an injury doubt for the United States' CONCACAF Nations League games against Canada and Cuba.
Pulisic suffered a hip injury in victory against Crystal Palace.
The 21-year-old attacker appeared to pick up the knock when he scored his fifth goal in three Premier League matches, after colliding with goalkeeper Vicente Guaita for his headed goal.
Pulisic became just the fourth American to score in three straight Premier League games, after Roy Wegerle, Joe Max-Moore and Clint Dempsey.
The U.S. Soccer Federation said on Monday that Pulisic continues to be evaluated and no decision has been made whether he will join the U.S. camp in Orlando, Florida.
