Miami Heat guard Kyle Lowry has been ruled out of Game 1 of the Eastern Conference Finals against the Boston Celtics with a hamstring injury.

Lowry, 36, averaged 13.4 points, 7.5 assists and 4.5 rebounds per game in 63 regular season starts, but has been plagued by injuries in the postseason.

Miami's point guard initially suffered a hamstring injury in Game 3 of the Heat's first round series against the Atlanta Hawks, missing the remainder of the first round and the first two games of their round two clash against the Philadelphia 76ers.

Lowry scored zero points in his return for Game 3, and then re-injured his hamstring in Game 4 as the Heat lost both games before rallying back to win the series in six.

Game 1 against the Celtics will be around 10 days removed from the aggravation of the injury, and given the timetable of hamstring injuries, particularly in older players, it can safely be assumed Lowry remains at least a week away from a possible return.
