Jozy Altidore says his sprained ankle is getting better, but he left the impression it hasn't 100 percent healed ahead of the United States' World Cup opener against England on Saturday.

The 20-year-old forward hurt his right ankle in training June 2 and missed last Saturday's exhibition win over Australia. He resumed full training on Tuesday.

"It's getting better for sure," he said after practice Thursday in his first availability following the injury. "I didn't think I had anything that serious to the point where I'd have to be relieved from the tournament, so I'm happy about that."

With Altidore out, Edson Buddle and Robbie Findley started at forward against Australia.
