Robinson was injured late in the first half against the Sixers. He limped to the locker room and was declared out for the rest of the game.
Robinson has played in all eight games so far and is averaging 6.5 points, 6.4 rebounds and 2.3 blocks per night. He is coming off a relatively healthy season, appearing in 72 games last year after being limited to 31 in 2020/21.
Isaiah Hartenstein, who started the second half Friday night, should see a larger role while Robinson is sidelined. The Knicks also used power forwards Julius Randle and Obi Toppin together against Philadelphia and may employ more of that small-ball lineup until Robinson returns.
