PRETORIA, South Africa — F Jozy Altidore ran sprint after sprint while a fitness coach looked on.
He was held out of Saturday's exhibition win over Australia, three days after spraining his right ankle in training, and he tested the joint Sunday as the U.S. team held a light workout at Pilditch Stadium.
"It seems like he's getting a little bit better," G Tim Howard said. "It's going to be sore, of course, but we've still got a long way to the game, you know, a long way in terms of needing time to heal. I think he'll be fine, but again, that's barring any setbacks."
Altidore, 20, wasn't available to reporters.
While coach Bob Bradley left training without speaking to the media, he responded to questions in an e-mail through spokesman Michael Kammarman.
"Jozy has been able to add to his workload every day, which has been positive," Bradley said. "We are pleased with his progress and will continue to move him forward. The team has a day off (today), so we have another opportunity to work with him individually and gauge his status for training."
If Altidore isn't healthy for the Americans' opener against England on Saturday, options have emerged. Edson Buddle scored his first two international goals in Saturday's 3-1 victory. Herculez Gomez got the other goal. And speedy Robbie Findley stretches the defense, even if he missed an open net and hit the crossbar.
"All the talk surrounding training camp was that Charlie Davies was injured, and it gave an opportunity with some new faces," M Stuart Holden said. "We've seen that all these players can contribute, and it's nice to know you have guys that can come in and score some goals and provide a spark when they need it, or even play from the start. And it speaks to the strength of our squad."
Meanwhile, England star M Frank Lampard sees a dangerous foe in the Americans.
"They'll be very organized," Lampard said. "There is a certain rivalry considering the players they have who play in the (English) Premier League. It'll be a tough game — the first one always is.
"Considering we're playing the strongest team in our group, other than us hopefully, then I think it'll make for a tight game."
