Detroit Pistons big man Isaiah Stewart has been ruled out of Game 4, the team revealed before their playoff matinee against the New York Knicks April 27.
Stewart missed the Pistons' final two games of the season, and Games 2 and 3 with right knee inflammation. The fifth-year forward is the backbone of the Pistons' defense, and tried playing through the injury in Game 1 on April 19 before subbing out of the game for good early in the fourth quarter.
Pistons coach J.B. Bickerstaff said Stewart is "day-to-day" going forward.
