In fact, neither the Galaxy nor the U.S. Soccer press releases announcing the 24-player roster even mentioned the knock that forced the influential U.S. playmaker out of this weekend’s Galaxy game in Carson.

The Galaxy did not immediately respond to an email seeking clarification.

Here’s what U.S. coach Jurgen Klinsmann reportedly said about the injury in a conference call today:

“He was supposed to do an MRI this morning in LA and he skipped it because it improved a lot during the day. We spoke last night and he said that if it is even better in the morning then he would skip the MRI and come straight to Miami, which is the case.”

Notable: Former Chivas USA midfielder Sacha Kljestan is recalled to the U.S. squad for the first time since the Italy game in February, while former Galaxy and Chivas USA foprward Alan Gordon will seek his first U.S. cap after notching a career-best 13 goals and eight assists in 23 games for the San Jose Earthquakes this season.

From the Galaxy:

Donovan is the fifth Galaxy player to leave the club on international duty during the current international window with Robbie Keane (Ireland), Dan Keat (New Zealand) and Christian Wilhelmsson (Sweden) all representing their home countries in World Cup Qualifiers while Jose Villarreal is with the U.S. Under-20 National Team at the Marbella Cup in Spain.

*Chivas USA defender Ante Jazic has been called into the Canadian National Team squad for its World Cup Qualifiers against Cuba and Honduras, while midfielder Oswaldo Minda has been included in the Ecuadoran National Team squad for its games against Chile and Venezuela.
