Injured Heat forward Mike Miller missed Monday's practice to visit a doctor for more treatment on his sprained left ankle and is likely to sit out at least the first two games of Miami's upcoming three-game road trip. Miller won't travel with the team on Monday to Orlando to start the trip. Miller, the NBA's leading 3-point shooter, sustained the injury in the first half of Saturday's home overtime victory against the Indiana Pacers when he landed awkwardly. He immediately hopped off the court and directly to the locker room for an X-ray.
