Striker Jozy Altidore, who has been sidelined with a strained hamstring since the United States' 2-1 win over Ghana on June 16, joined the U.S. team on Monday for a workout in Salvador, and is fit and ready to go, according to U.S. Soccer.

Altidore has spent the past week jogging separately, but on Monday he warmed up with the team for a portion of training. The U.S. plays Belgium on Tuesday at 4 p.m. ET (ESPN/WatchESPN).

"We are very optimistic," Klinsmann said last week when asked whether Altidore might be ready to play Tuesday. "Every day is a big step forward for Jozy. It's 11 days now [since he got injured] and it's looking better every day, so we're optimistic to have him being part of the Belgium game."
