Manchester City midfielder Claudio Reyna went off injured in the 16th minute as the USA were beaten 1-0 by Morocco in a World Cup warm-up game in Nashville.

The USA captain suffered a hamstring strain but is hopeful of being fit for the tournament in Germany next month.

Reyna told ussoccer.com: "I'm going to get an MRI, it is close to the games, so obviously it is not the best timing but I'm hoping I've gotten away with something very minor. I'm optimistically thinking it is not going to be something long term, but tomorrow I will know better."
