National Team Call Up for Morsink?

I received this link today about Wizards midfielder, Kurt Morsink. The article is basically talking about an upcoming tournament that the Costa Rican national team will be competing in November 17th through the 19th in Oman. According to the article, the coach of the national team has named Morsink as one of the players that he would like to bring to the tournament with the team. It's the week after the Conference Finals, so should the Wizards allow Morsink to go, he'd likely miss the Eastern Conference Final. The team does not have to let Morsink go, though, if they don't want to. The game is not on a FIFA international window, so the Wizards won't be forced to release Morsink if they don't want to. Will be interesting to see if he is actually called up, and if he's released by the team.
