The United States pre-World Cup training camp may be opening on Wednesday, but the expectation is that there will be at least a few players who don't report until a little later. Sporting Kansas City's Matt Besler and Graham Zusi have a league game on Wednesday against the Philadelphia Union, Toronto FC's Michael Bradley has a Canadian Championship game against the Vancouver Whitecaps on Wednesday and AZ Alkmaar's Aron Johannsson has a pair of Europa League qualifiers on Thursday and Saturday.
Besler effectively confirmed that he and Zusi will be allowed to join camp a day late via Twitter.
Still lots of work to be done!!Looking forward to this huge opportunity and can't wait to join the team on Thursday #USA— Matt Besler (@mbesler) May 12, 2014
Going off that, it's a safe assumption that Bradley won't be required to report immediately and it has long been assumed Johannsson will be allowed to remain with AZ until their season is officially over. One Toronto-based reporter even suggested there's a possibility that Bradley wouldn't join the USMNT until Sunday.
Somewhat complicating all of this is that it's not entirely clear when the FIFA-mandated reporting date is. Generally speaking, the understanding is that players are required to report once their club season is finished, which likely means Johannsson won't report any earlier than May 19. But for players in places like Mexico and MLS where the leagues are still going, there's little clarity and those situations are usually left up to the club and national federation to negotiate.
