Jurgen Klinsmann has made it clear he plans to invite all 30 players who are named to the preliminary United States' World Cup roster to the start of next week's training camp.
The U.S. coach might have to wait a few extra days for a few of the World Cup hopefuls to arrive, including forward Aron Johannsson.
While the club season ends this weekend for many of the Americans playing abroad, several players have club commitments extending beyond the opening of camp next Wednesday.
"It has priority that they get the job done with their club teams before they come into camp," Klinsmann said in a recent interview with the U.S. Soccer Federation website. "So, we might have a few guys coming in a couple of days later than we expected them, but that's all right."
Johannsson, who has 26 goals across all competitions this season for AZ Alkmaar in the Dutch league, has battled an ankle injury lately and missed the first leg of a semifinal playoff game at home against Heerenveen on Wednesday, with the return match scheduled for Saturday.
If Alkmaar advances to the finals, which determine placement in European competition next season, he likely would miss the opening of training camp at Stanford University.
Another American hopeful who could be delayed by his club's season is Timmy Chandler.
The Nuremberg right back returned to action April 26 following knee surgery in February, and he played the entirety of a 2-0 loss to Hannover last weekend. However, with one German Bundesliga game remaining, Chandler's club is in danger of relegation.
Nuremberg, which closes its league season against Schalke on Saturday, is currently 17th out of 18 Bundesliga teams — one point ahead of last-place Eintracht Braunschweig and one point behind Hamburg.
The bottom two Bundesliga teams are relegated to the second division, while the 16th-place team faces a home-and-home playoff against the third-place team from the second division for a Bundesliga spot next season.
