The New York Knicks may be without one of their key players in Sunday's game 4 matchup against the Detroit Pistons.

The Detroit Pistons will be without center Isaiah Stewart for a third straight game because of a knee injury and the New York Knicks say center Mitchell Robinson is available to play in Game 4.

It was a bit of a surprise over the weekend when an unexpected name cropped up on the Knicks' injury report: center Mitchell Robinson, whose impact on the opening-round series agaisnt the Pistons has been limited, but who is still a key because he is the only legitimate center in the Knicks rotation.
