Miami ? LeBron James was one of the last to leave the Miami Heat practice floor Friday, after a long free-throw-shooting contest with rookie Da’Sean Butler.

That was the extent of James’ workout.

The NBA’s two-time reigning MVP sat out practice as a precautionary measure, three days after leaving a preseason game due to cramps and pain in his right hamstring. The team expects that James will be ready to resume practice today.

Other Miami players sidelined Friday included guards Dwyane Wade and Mario Chalmers.

Wade was in Chicago testifying in a trial that’ll decide custody of his two sons, and the Heat hope to have him back at practice next week as he recovers from a strained hamstring. Chalmers has had recurring stiffness as he continues recovering from a high-ankle sprain. Wade is expected to continue testimony Monday, though he might resume on-court workouts as early as Tuesday.

Jamaal Magloire, Eddie House, Carlos Arroyo and Shavlik Randolph have also been dealing with some nagging injuries.
