USA manager Bob Bradley has confirmed that Jozy Altidore will be available for Saturday's clash with England.
The striker missed a warm-up game against Australia over the weekend as he recovered from an ankle problem.
However, he has since resumed training and will be fit for USA's opening Group C game against Fabio Capello's side.
Bradley said: "The injury cost him a couple of days (training) but, from the start, we knew it was very minor.
"The fact he is back in regular training means he is available for whatever role we choose on Saturday."
Bradley is also optimistic that key defender Oguchi Onyewu will be able to complete 90 minutes against England if called upon.
Onyewu has just returned to fitness after suffering a patellar tendon injury seven months ago and did not complete any of USA's three warm-up games.
But Bradley said: "The fitness programme that we have put our players through for the World Cup means all 23 players are ready to play 90 minutes on Saturday if asked.
"It is a credit to our staff and the players because they have worked incredibly hard."
