Skipper Reyna plays down injury
I'm hoping I've got away with something very minor
Claudio Reyna
USA skipper Claudio Reyna is confident of being fit for the World Cup despite suffering a hamstring injury in the 1-0 friendly loss at home to Morocco.
The Manchester City midfielder, who has been sidelined for much of the season with ankle and shoulder injuries, lasted just 13 minutes in Nashville.
"I stretched out for a ball and it just tightened up on me. As a precaution, I came off," said the 32-year-old.
"I'm optimistically thinking that it is not going to be something long term."
Reyna, who will have an MRI to determine the extent of the injury, added: "I'm hoping I've got away with something very minor."
The outing was Reyna's first for his country since September 2005 when the Americans beat Mexico to secure their place in Germany.
He subsequently broke his right ankle in December and missed eight weeks of the season only to injuring his shoulder three games into his comeback in March which ruled him out for a further four weeks.
Reyna has scored eight goals in 109 international appearances and has played in the last three World Cups, although he sat out the opening game in 2002 with a quadriceps strain.
The USA start their 2006 campaign against the Czech Republic in Gelshenkirchen on 12 June
