All Whites midfielder Ryan Thomas has been ruled out of the tour of the USA after suffering a significant haematoma to his quad muscle.
The promising 21-year-old, who plays his football for PEC Zwolle in the Netherlands, was rated a 50-50 chance of making the tour by All Whites head coach Anthony Hudson on Thursday and has been ruled out on the eve of the team's arrival due to a haematoma. He is also recovering from a knee injury.
Thomas, who has played five internationals for New Zealand, is replaced by Wellington Phoenix midfielder Louis Fenton in the 23-man squad.
"It's a shame for Ryan as I know he was desperate to play on this tour and get back into the All Whites environment," said Hudson.
"We wish him all the best in his recovery and hope to have him back for our home qualifiers. Ryan's injury is unfortunate for him but we are pleased to bring Louis Fenton back into the squad. The door has opened up for him, and we every confidence that he'll come straight in and do well for us."
The All Whites play two international friendlies on their tour of the USA. They face World No 14 Mexico in Nashville on October 8 and then meet the World No 26 the USA on October 11 in Washington DC. Both games are live on SKY Sport.
