New York Knicks center Mitchell Robinson will be out at least a week due to a sprained right knee, the team announced Saturday.

Robinson suffered the injury in the second quarter of Friday's win over the Philadelphia 76ers. He will be re-evaluated in 7-10 days.

Robinson, who signed a 4-year, $60 million extension with the Knicks this summer, is averaging 6.5 points, 6.4 rebounds and 2.3 blocks this season.

He will be replaced in the lineup by stalwart reserve Isaiah Hartenstein, who joined the team as a free agent in the offseason.
