Two games into his return from December ankle surgery, Mitchell Robinson is out of the lineup for the Knicks with an injury to the same ankle.

Robinson suffered a sprained left ankle in Friday’s loss in San Antonio, and he has been ruled out for Sunday night’s game against the Thunder at the Garden.

Robinson played 19 minutes Friday night against the Spurs after playing 12 two nights earlier in Toronto in his first appearance since Dec. 8.

Julius Randle (shoulder) and OG Anunoby (elbow) remain out for the Knicks, although Alec Burks (shoulder) and Isaiah Hartenstein (wrist) were available.

All-Star guard Shai Gilgeous-Alexander (quad) was in the lineup for the Thunder.
