The New York Knicks say Andrea Bargnani has a strained right calf that will prevent him from making his season debut Saturday against Philadelphia.

Bargnani was hurt Friday during practice and an MRI revealed the injury.

The former No. 1 overall pick strained his right hamstring early in the preseason and had finally appeared near the point of returning. He has battled injuries since coming to New York from Toronto in a trade and hasn't played in the regular season since January, when he tore a ligament in his left elbow.
