X-rays were planned, the team said.
Foye's absence added to the Wizards' growing injury woes at guard. Mike James will miss at least the next month with a broken left ring finger, Mike Miller sprained his left shoulder last week against the Heat, and Javaris Crittenton has a left foot injury. Forward Antawn Jamison (shoulder) is also sidelined.
Wizards guard Gilbert Arenas is battling a calf injury, although he was in Washington's starting lineup Tuesday.
